"The plant 70-200/2. .8 Analysis and comparison of the lens. " .
--Excerpt from the Chinese photographer-photography Forum — in ldc101 moderators ".
Recently we referred to this subject, "agenda" on a small steel gun around, black (Sigma 70-200), white, small white ... ... and so go on, but white is the joint on issues, including elder brother William, if Yu Xiong, Mirage 2000, brother and other friends have felt the need to put them together, "a fight", so that the most used focal length of the segment has a comparative concept. .
For this reason I looked at the number of "stockpile" materials, such as "portrait lens" ten edit a set of common 70 (80)-200/2. .8 ( F4) manufacturers representative lens for yingyoumen reference.
In this first statement:. .
1. ±?ì? × ??óóé purely fusion to several industry friends view one, subjective and one-sided weakness, "many," better Pen ' very little ", we can only be deemed to be more than a pastime of tea, 000 is not so absurd," mislead "people;.
2. No quote for any of the manufacturers, merchants advertise the intention, but as always, adhere to the "objective, fair and true peace," the 8-word approach to "Friends of services for the majority of Shadow" as the only object and purpose;. .
3. The information in the text, a picture source editing involved a variety of channels, but are open to the public, there is no interest-driven dictates. If reproduced, without consent of responsibility.
Gossip said that the body started (by typing the speed limit, fear of the "ruthless little sister" to kick, only to paste a paragraph, please understand):. .
1. Survey:.
Section 70-200 of this focal length lens has been the various critical battleground, the one is the focal length of the segment is very popular, second only to be sold as a standard focal length lens 28-80 segment, the success or failure of life and death of solidarity. Furthermore, the development of this section of the lens has been a long time, the optical structure has been well established, and in order to maximize the image quality of the lens to achieve a considerable level, virtually every family and the generous application of the image in the lens inside the focus, low dispersion glass and so costly technology, constant aperture destined to make this product a high price goods. .
However, the original manufacturer, there is no doubt their optical technologies is a leading, in order to meet the demanding professional user satisfaction, and their products in the mechanical and optical on the best level for a lens like this optical products, their most critical is to constitute the lens glass lenses. It is a well-known fact that a good German lens comes mainly from the use of short glass factory of optical glass, made the world's best optics products.
The camera no matter how hard the Japanese are still not a small gap, which is the power of the glass. Now for the original and the Deputy factory lens, also has such a claim. Lens Plant in Japan like Nikon, Canon, Pentax has its own glass so the lenses of the formulation and production process are highly confidential. .
In Vice factory, glass production is the highest level of tuli, ED glass and many well-known manufacturers use. But do not know why, tuli itself rarely use this upscale expensive material, but the production of large-diameter ED glass production, the top three in the world, like the single with a diameter of 300 mm price on 70000 yen or more — you can have several of the world have such a capacity.
Another is the design capacity. In the optical, the Japanese design is undoubtedly the strongest ability to Canon's optical research and development center, especially in the last few years, Canon's pioneering work in optics are many, though not yet established with Chase than the achievements of the classical structure, but true leader in the applications of various plants of 5-10 years. In the very important aspects of electron optics technology Canon has in many key patents with decisive force, just as ultrasonic motors, the start of the plant patent is limited, spend a lot of time trying to develop a kind and The counter technology.Results in less than 5 years, including Nikon, Minolta AF these have the capacity to provide the camera manufacturers are already close to ultrasonic technology and comprehensive. (Until now, this trend is also being constantly being shown).
In Japan, there is a design and a strong reverse-engineering capabilities of the manufacturers - Sigma. This is a short history of professional lens factory, started a design center that came to rely on. Their strength lies in the capacity of the reverse design is very strong feeling that we should be, no matter what original introduction of new technology, he was always the first follow-up.The company's weakness is due to the history of production and management experience, they shot at an early stage are not durable, or poor-quality machinery, which is compared to the Dragon and sturdy, tuli really helpless; now there must be improved, but the impression of incidents, it can be reversed, not to mention today shima lens processing quality is still not and N, c, and so companies compete.
Second, the quality of the lens lies in the low dispersion glass:. .
To emphasize low dispersion glass quality. Now the camera often said how much they use low dispersion glass block, however, the manufacturers of low dispersion glass is a high level lower.
Start with fluorite glass, which is now the best of nature with low dispersion optical material, the main component is calcium fluoride, which is a very high chemical stability and chemical substances, acid and alkali, it is not easily dissolved in water . Because of this, very little natural crystal, artificial crystal is difficult, the biggest drawback is the fragile, difficult process, anti-vibration capability poor, so the military is the use of magnesium fluoride to replace him to produce infrared missile hood. The use of fluorite in the camera lens to produce lenses that only Zeiss, Leica and Canon.Other manufacturers are mixed with special low dispersion glass to achieve, on the one hand, the purpose of this is to minimize dispersion, another aspect is to avoid the use of calcium fluoride glass, so that the camera's ability to withstand harsh environments to reduce.
Since most manufacturers are using a mix of glass, the plant's products will inevitably bring about differences. In the mixed glass, Canon's super UD is the best, it has close to the optical properties of fluorite, but there are ordinary optical glass processing performance and reduce production costs significantly. However, the application of the lens is not much, but with Canon's new products look like or can not replace the fluorite position. But relatively speaking, since the use of fluorite products may be less and less, should be replaced is the Super UD. .
Canon has a UD glass, and Nikon, Pan Pacific Comox, Olympus with ED glass is the same type of thing, this is far the most mature production technology products. But the fact that several of the optical properties of or not all the same, on the whole, can only say basically the same. Adoption of such quantity of glass, the comparability with sibling can be regarded as having the same efficiency.
For each deputy factory, their position and on the economic performance of value, so that they can use this relatively expensive material with some tone on: first, Tu Lili raw materials with their strong production capacity, developed a more cost low, with low dispersion material and widely used. However, such materials are also divided into several types: SD, SHD, etc.. .
Tenglong more cost that: their LD lens is not a generally low dispersion lens, only a low dispersion in..
For Sigma, the lens it also has several now widely used and also similar to the Tokina Tamron, but slightly higher than they, and the original, but still a considerable gap compared to. Sigma is also an ideal low dispersion ED glass is roughly equivalent to the glass, but only as far as I know it's 180 / 3. .5 Use of a macro lens, but The lens becomes very high prices, and the lost and the original products price competitive. .
The difference between low dispersion glass, including the pros and cons of the camera can also be seen from the structure: low dispersion glass should be used in the camera's most thick lenses. If this is not the case, and low dispersion lens use rarely, for example, only one piece, that is, just like the Nikon 70-earliest 300ED, that can be said to be deceiving consumers by advertising.
Moreover, such lenses as fluorite and other lenses generally can not glue, can be used independently, low dispersion lens is so good. Performance indicators for the functional design of the same lens, the lens the more the more excellent, it is mainly a single lens for each reduced the difficulty of processing, more precisely to correct all the aberrations, but this again the level of the plant's coating serious of test. .
Third, the lens of vacuum coating:.
Test run in Japan, now the world's production of various lens coating plant to Canon, Fuji, Rollei three best, they can easily produce more than 9 or more multi-layer coating. The remaining Pentax's SMC 7 layers, Chase T * 6-layer, Nikon mc, etc. are very good. .
Vice factory lens coating is the highest level of the Dragon, it has certain than the original manufacturer of coating technology. But like Ricoh these manufacturers, including its award-winning GR1-28/2. .8 lens is 3 ~ 5 layer only. In much of the three lenses, Vice factory, shima. It's many film through efficiency slightly lower than other manufacturers, the trouble is, it's solid performance coating in high humidity areas has always been a lack of praise, such as Japan, Hong Kong, Chengdu, and so on. This is also why it's the lens with the ages, the performance degradation was an important reason. In the secondary market, Sigma's lens is often the most inexpensive and not that important. .
In telephoto zoom lens variety, choice a lot, but for really suitable and practical not imagine that much. For whatever it is for the amateur or professional, this choice is mostly on the distance should be 70 (80)-200 (210), or 100-300. Now all the 75-300, 28-200 zoom lens, the image quality, there is still a big problem, the Eagle both belong to a waste of money stuff.
The most promising is that everyone is 70-200/2. .8 Such a "big guy." Such lenses are now the best zoom lens inside the lens. Caliber, high image quality, but also the most commonly used and slightly sub-level of f / 4 product is the bottom line is acceptable. .
IV. the common brand lens for simple evaluation:.
Following some hasty comments on several products, but his words will inevitably be too subjective, we would have a brick fly CAREFUL IN THE SUMMER. .
1. First of all say that Nikon, Nikon 80-200 this focal length segment launched a total of 5 generations, the earliest Ai-S very rare, the price performance has a mysterious, but according to the first generation of AF to guess should be comparable. AF version generation, second generation optical structure exactly, just to improve the mechanical design problems are two different products, they are mainly the position of the lens hood. Overall, this lens is very successful, in spite of the problems in the mechanical, Imaging is not responsible for the Nikon on down for many years. Things that are unique at that time, in addition to slightly behind the year's EF 80-200/2. .8 L, the back is also worthy of the name is Swordsman. .
Really perfect is Nikon's third generation AF80-200 lens, this generation of the original unreliable single ring structure into a ring structure, joined the (false) focusing, internal zooming, this is a mature product, which is now commonly known as "little Cannon fans (XGP)", the lens than the previous two generations on the image quality has been greatly improved, there are 3 block ED glass help, imaging, Nikon taste, in the sales price is also not use expensive policies, moderate price attractive, even a lot of uncertainty in NC-fans go, extraordinary charm . .
The fly in the ointment is the XGP 200mm focal length large aperture imaging quality declines, as well as its large aperture scorch-imaging effects less, resulting in a lot of criticism.
Later, under the powerful offensive Canon, Nikon once again launched a new generation of AF-S 80-200, but you can see that this is a very mature product generation, despite the application of as many as five ED glass optical performance increase is very limited, many ways, less than previous models. Although the focus with a more rapid silent ultrasonic motor, but the volume is huge and weight, although in our hands, look "extremely brilliant", but get up and feel able to balance the only F5. .
Seriously, this lens optical level are increasing, especially on the generation of up to 200 people has a focal length of performance gaps. However, it will be lost, in paragraph 80 of vist generation and current generation of imaging are increasingly going soft line, taste the "Nikon" less and less, making many N Home Home unhappy.
Therefore, the introduction of AF-S VR Nikkor70-200mmf2. .8 G, the view of the causes and the price of brand loyalty issue, N must be at home boss still has AF 80-200/2. .8 D ED N, and should not be rising with other home than the low. Because Nikon is the Nikon, but not others, unique. .
2. Then said the fate of Nikon's "the enemy" — the Canon.
After entering the era of Canon AF sudden force, and with excellent optical technology to seize the leadership of innovative technologies. Many lenses are the first to introduce professional fields, provide a very good L series lenses. However, the L is a pity that Canon L lens is the meaning of luxury, fire guns wildly stealing money;. .
Amateur level shots though many can give surprising, but there are a lot of people at the hut.
Canon's first 80-200/2. .8 L lens is a complete professional machine was introduced EOS-1, although the high price (at that time the most expensive, it really deserves the name L), but the image is very good, AF speed is to present standards see also the quick. Soon as the Canon professional photography in a vast world, a spit for years to suppress the foul smells by Nikon. .
In ultrasonic motor technology is mature, Canon once again launched a powerful 70-200 lens, and later with anti-shake technology IS lens, the two lens no matter from that point of view, is excellent. To date, has not yet had its, well deserved the title of Emperor mirror. If you do not have innovative technical import, beyond this header is empty words.
No wonder so many years the factory, the lens prices change a little, but nowhere in the secondary market is difficult to find, this definitely see the level of users. .
However the two lens resolution than 80-200 years seems to be weak, but there is no sharp of a small increase, so the overall performance of a lot, especially in the end, reached 200mm focal length can be comparable to the level of focus.
Canon also did not give up on mid-priced camera market development, known as the "little white" of the 70-200/4L is such representatives, this lens is priced at about half white, for many cash-strapped Friends movie has a very strong attraction. .
Many people see this lens uses the calcium and Super UD lenses, think this lens will be better than the white, in fact they missed a very important issue: the lens resolution and maximum effective aperture, diameter, the greater the larger the light, the more information is collected, the appropriate resolution. Although some other optical, this rule is not disproportionate, but it is quite obvious.
After many tests proved the small white or slightly inferior to white edge. Even so, when a small white imaging is still very good, not because it is cheaper than white would look down on it. Although it lacks the focus of a large one outside the virtual aperture of unique effects, this is not a big deal, especially for those who shoot landscapes and carrying travel, and its light is very attractive small. Little white lies on sale when the mistake is not attached tripod ring, sold separately profiteers asking for two thousand dollars, almost half the lens! Something that makes the NPC vexing problem, especially with some lighter body and his time with. .
Canon will be applied to the fixed lens "after the Group focus-" agencies go into "content-type" set-focus (midway lens group to move only), and in 70-200L on high-rate variable coking and lightweight.
According to Canon Lens Work description, within the group focusing type has the following advantages:. .
1. Because the only mobile lighter lens group, so the auto focus very quickly, manual focus is also very light and handy;.
2. . Lens length does not change because of focus;. .
3. Implementation of a lens system overall lightweight;.
4. . Filter frame does not rotate;. .
5. When af af-looping will move forward or backward.
3. The following describes two other princes begin - Minolta and Pentax. .
Now the Minolta and Pan Pacific Comox end-users, with 80-200/2. .8 this very expensive lenses is the odd man out.
Minolta people at home are often ignored, that it not be professional enough, the lens is also not good enough. But in a foreign country that is a mystery, it 80-200/2. .8 G is a high quality lens, but it is in many tests ahead of the Nikon 80-200 (2 generation) and EF 80-200/2. .8 L. .
Its size and weight of this constituency is a definite advantage. However, its price is high also makes it difficult to accept the main reason.
Pentax's even more rare, but the Pentax's yearbook I was not rare in his shadow, it is a great lens. .
Pantax SMC FA * 80-200/2. .8 ED [IF] — high lens.
In the last part of this topic in the table, everyone will be able to see: it's score and the evaluation results are not satisfactory, compared to its high price, people think it seems incomprehensible. .
But the benchmarks and application is different after all, it's that do not have a right of the evaluation score "Photodu loudly condemn".
Although I have no chance of this lens directly used, but the Department of the Xinhua News Agency photographer friend of very respected in this head, I have been with him than the film: the same time, same place, with the object (stage performance), not allowed to use a tripod, flash, out of the film and compared to my Nikon XGP can only use "beats" words to describe. .
In particular, full open aperture when f2. .8 stage image resolution, color restore and let you truly convinced it is relative to the noble price. XGP.
Therefore, not all depends on the evaluation of the lens MTF scores and the like, it is a test condition, usually infinity focus, and practical application of state sometimes be greater than differences, in this lens is a typical case. .
The head of the biggest advantages in the full open aperture contrast, coke-imaging, restore the corner resolution, color, etc., in the same lens in the well-deserved belonging to superior.
4. Now the lens of the Deputy plants. .
This is one of the most disputed issue. Because each photographer has his own views and experience, a transcendent position, impartial and objective manner, will still have fans feel unbalanced, for instance — these are the comments of the Deputy plant 70-200/2. typical features of .8 lens.
Only the faithful in the shadow of expectations, encouragement, and encouragement, the unpleasant task to elaborate. As far as possible without any orientation and emotional. .
In recent years, Vice factory in shima Thunder Zuijin, advertising, awards, like the European camera lens awards awards did not seem too great, "Nugget" there is only the commercial significance of larger Bale.
Sigma's 70-200 lens is no doubt that away than the Canon - the best school to learn. .
On the shima, made like 70-200EX HSM lens for this quite difficult, and the price is not very high.
Its optical structure and Canon's white is almost the same nature, and electrical parts of imitation was also bigger way, and the Canon body to use up very well;. .
This is a very good lens Imaging — but is surprisingly good. Mechanical properties is said also that it's mirror, you can always get a little thin feeling (shima no mechanical properties of Fame, I saw many renovated shima lens, illnesses, and lack of concentration, which can prove that it is the low level of overall processing);.
So there is an extreme view: XH is the only all Sigma lens and manufacturers, "strong words" shot. .
I wonder if you have not noticed that a lot of second-hand shops boss shima lens selection and evaluation of? these are best thresholds, shima lens optical system that is easy to use one or two years ago, followed by a careless once or twice, fall dramatically unhinged.
The fear is that the lens coating visible mold - "Sigma lens mold-prone" is the industry's tacit open secret. .
Also, why can feel everyone: there was a "child" shima? almost every shop is like selling a product, shima is really very nice of them?.
I am this person a little rebel and a lot of stores all the things I strongly recommended to be vigilant, there is a problem - reportedly sold a Sigma 70-200 per store profits generally reach "selling a Canon's 70-200 lens twice, "so much, so this is what they recommend," reason "(business friends have to call me up). .
A bunch of stuff about that, to be fair, if enough "original factory complex", this lens or shima is very good, reached a very high standard, the image is actually very close to their original factory level, color reproduction is also good.
For use with lenses Dehen, for equipment for faster user is still very applicable (these words is not to say that the "loss" a little?). The special status with his best time, good conditions for preservation, using very few users also good, is an ideal choice. .
5. Now it's your turn to say tuli:.
Figure Korea and fitness Ma Xuejia to the opposite road, take the path of the complete Nikon. .
Tuli's 80-200 is the cheapest, but also very heavy, metallic components are sufficient. But it seems it is too stingy to low dispersion lens, giving it a shot of the factory some than others. Its contrast relatively large, a bit like Nikon imaging, 70-200-well, obviously, should be reduced to very good effect of achromatic.
I tried the Tokina 80-200 lens was not found, as some friends that are yellowish film phenomenon, it is a flint with a high-refraction glass containing only some of the phenomenon. Most of this glass used in the wide-angle lens, telephoto lens should be no such phenomenon. .
On the whole, comparing the TOKINA lens flare, a bit heavy and clunky. In addition the focusing ring sliding clutch-AF/MF switch device, it can be considered a unique design, it was appreciated, but most people are not easy to use, and speed might be the slowest one!.
Incidentally, the 100-300/4 for Tokina lenses, said a few good words. Rural adults have said: This is a good lens, even the Canon EF 100-300/5. .6 L Du catch up. Although the price of your points, but you have your truth, in this paragraph only focus is the most choice. Sigma 100-300/4 although the new lens is also introduced, but you can assert that the machinery will not achieve this level of the lens. .
Tuli ATX80-200/2. .8 lens models are: AF-ATX 828 Pro.
f2. .8 Constant aperture, generally OK, 17 11, group structure, an SD lens, lens diameter φ77, recently focusing distance of 1. .8 Meters. .
ATX Pro series lens grip is a solid, stable; a gold ring on the front to show that it's identity. Focus ring in front, zoom in, zoom ring rotates very smoothly (feeling than "good" white "also). Accompanied by a cylindrical lens hood, just slightly shorter. Text marked clearly audible. Tripod attachment.
The inside mirror is designed to focus, filter ring does not rotate (filter diameter of 77mm), the length of the lens does not change with the zoom. .
I've seen is the Canon lenses found in interface EOS-3 fuselage could not autofocus, EOS 50 on normal operation (want to buy this mirror of the photographer, it is necessary to pay attention to the latest issue of the fuselage of the match).
Load to the fuselage, the auto focus is still very quiet voice, but somewhat surprisingly slow pace, than the "white" of the co-coking time is almost twice as slow. .
Focus distance is 1. .8m, than the "white" 1. .5m to far a piece, and Sigma 70-200mm f/2. .8 in much the same, the HSM macro magnification, loses.
Image quality is also good, but the short distance, the residual spherical aberration correction was not enough, so that image quality has declined;. .
Similarly, the Tokina ATX series-specific "af clutch mechanism" is also applied on the lens in this — in addition to the lens has a familiar proximal AF/MF switch, the focus ring is marked with the AF/MF switch.
Methods used are: the focus ring turning left and right click, to take themselves forward and will be changed from AF MF, MF switched to the contrary by the AF. Hope that the very mobility of users can be their eyes off the viewfinder, while the left-handed push-pull converter AF / MF. However, and "full-time manual focus" or nothing. .
Although the mirror Rigidity (stiffness), without doubt, however, due to the slow AF and AF/MF focus clutch design, in the performance of the overall score, in the full five star rating, only won three and a half stars.
In this section of the final map Korea, Korea, and Sigma tell you chart a practical comparison:. .
A friend of mine had tuli 80-200F/Gold 2. .8 and shima's 70-200F/2. .8 APO compared, the result is a comprehensive end-to-win 80 tuli, whether large or small aperture iris are strong than shima; 135 focus segment almost, but the sharpness of the shima tuli; more than 200 end big aperture shima Central clarity better than tuli, but better contrast, tuli smaller aperture shima tuli better than after.
6. Here comes the Dragon began. .
The Dragon is the most low-key, now all of its energies to the development of the mainstream market, high zoom lens, illustrates the farewell high definition professional lens at a high price.
I see there was a Tamron SP AF 70 - 210 / 2. .8 LD lens, the quality of flat, there is no characteristic imaging moderation is still the 200mm focal length of the side a little worse, but can also be considered plausible, and now has not seen sales. .
Beyond and above the lens, so in this separate lists its arguments and evaluation for consideration:.
The lens in 1992 / 5 launched; lens structure 17 of 13 group; aperture blades 9; diameter 77mm; Closest focusing distance of 1. .5 M; Dimension 90x177. .5; Weight 1320g; current price should be around 5,000, but has not been there a long time merchandising;. .
Xiping British health evaluation — operational ★ ★ ☆; resolution ?? ?? ?? ??; actual filming ?? ?? ?? ??; price ?? ?? ??; total score ?? ?? ??;..
Later in the third quarter of 2003, Tamron announced the launch of five in one fell swoop for the digital use of new series designed for full frame camera to "Di" for the type label, which AF28-75 / 2. .8 To cost-effectively in the market to buy off a burst of enthusiasm, but the paragraph in which 70-200 are slow to launch after the announced parameters. Until another year and a half, Tamron announced that encounter more difficulties because of suspension of this lens development. .
Another silent after two years, when the people are no longer the only known as "the most lightweight 70-200/2. .8 lens" have any hope, it was in March of 2007 PMA exhibition and exhibition June P&E has unveiled the "rebirth" push the envelope. Two solo exhibitions at the samples look difference is: Beijing exhibition samples have the blue circle, a tripod, also made a change —.
According to available information the author of view, this is still a suitable full-frame digital, film the world's lightest dual-use large-diameter telephoto zoom lens. Will also be listed on Nikon, Canon, Pentax, Sony of four ring lens. And a few years ago camera technology has become more sophisticated and compact. The biggest change is the closest focusing distance from 1. .4 Meters into a 0. .95 M, the largest photographic magnification up to 1:3. .1, So the lens to increase the "MACRO" logo. .
SP AF 70-200mm F2. .8 Di LD [IF] MACRO design mirror group structure to 13 groups 18 pieces, of which 3 were LD low dispersion lens. 70-200mm corresponds to the focal length, minimum aperture value F32, Aperture blades 9, filter diameter 77mm. Volume 194. .3x89. .5mm, weight 1112. .6g. With Lotus-hood and aluminium quick release plate.
In the design of the Canon and Nikon mount lenses, the AF and MF can automatically switch the interface in the Sony and Pentax lens on the camera body to be controlled by the switch. However, in more than half a year later had still not seen The lens of where they sell. Tamron in this area appears to have been fully behind the Sigma and Tokina. .
Until January, 2008, in Las Vegas PMA show, this lens and three other lens again appear in the exhibition, the dragon has once again declared: "only the most lightweight 70-200/2. .8 lens" upcoming sales — and this is precisely the "Wolf!".
People can no longer believe that the Dragon again and again the announcement, this time determined to see the kind add. .
7. May also have friends concerned about the Vivitar Series 1 series cameras, is now to introduce its development process and status:.
Rise and Fall of Vivitar lenses -. .
1938, two Germans call Ponder & Best, maybe is a Jew, created the Vivitar, it has always been an American company.
Seventies and eighties Vivitar lens is from the Perkin Elmer Corporation by a group of designers running out of design, optimize the structure using large-scale computer (rumor is), was very advanced. The late seventies eighties produced a number of good shots reputation. It's the most OEM factory is being brought Kiron, Tokina there is also a processing plant, also in South Korea Samyang production. One argument is the serial number 21 at the beginning of the Nissan, 22 for the Korean production. .
Vivitar lens overboard production, leading to poor management and the shareholders changed hands a number of occasions. Therefore, the above statement are hearsay, are reliable and no one knows the truth.
a. . Vivitar's Series 1 Series produced better quality lenses, are listed below:. .
(1) 70-210/3. .5: first, only the macro in the long zoom lens, the largest 67mm aperture version is 1: 2. .2 62mm aperture version; the Tokina co., the maximum ratio of 1: 4 is the most rare.
(2) 35-85/2. .8: People drift through focus to achieve high image quality. .
(3) 48/24-3. .8:.
(4) 90-180/4. .5: Is called Making the best zoom (touch on even better than the AIS). Macro 1:2 is a true macro zoom head, flat like a field, working distance of 0. .7 Meters. AF 70-180 sooner than 20 years. Nikon is also the same period the production 80-200/4, was far ahead of Vivitar lenses only major giants. .
It's the size weight and AF 70-180 Basic, but Aperture is 72mm, perhaps because of 180-4. .5. His first wife was the lens hood with Series 1; stop only six piece, a little less. Af 180 degrees, 90 degrees, the zoom is very smooth, even in macro-and no focus drift. Fixation set of lenses, zoom is not extendable, equipped with a rotatable tripod jiehuan, most components are copper and steel.
The shot is VMC coating, but a reflection larger hood is useful, and the medium distance, the resolution at least as AIS 80-200/4. Close-up of 180 full-imaging soft, well after the close aperture. Working distance 0. .7 Meters, much stronger than the 70-180. .
(5) 28/1. .9: variable lens design, former group rotation, not Flex.
(6) 90 / 2. .5: Modern Photography magazine has two lenses of the highest resolution, one is a LEICA Sumikelong DUAL RANGE header, the other is it. 1:2 Macro head, special matching ring with three lenses to correct near-field after a difference of 1:1. .
Comment by David Ruether lens Nikon bayonet best macro. Tokina after production, the Tokina redesign this header for 90/2.1: 1, .5 PHOTODO scoring and LEICA Su m clone still an unbiased, and modern photography with the same result. It also Ponder on the packaging of the typeface: & Best.
(7) 135 / 2. .3: Vivitar produced in the previous 135 / 1. .5,135 / 1. .8, Said that the customer is NASA. .
(8) 200/3: up to 1: 4 (9) 600/8 fold back (10) 800/11 fold back.
b. . These are all the Series 1 series camera. There are some non-Series 1 Lens:. .
(1): 55/1: 2.1 .8.
(2) 135 / 2. .8 1:2 CF (CLOSE FOCUS): Vivitar Macro and close focus strictly distinguish between the two concepts, standard MACRO's must have a floating lens, to achieve flat phase field; but this is just moving the whole group, so standard CF. .
But this is the best workmanship Vivitar 135/2. .8 lens focus ring can rotate 540 degrees. At the same time, this is also the longest focal length close-up macro (AF 200/4 AF, close-up, when approximately 70-180 12cm smaller), the working distance 0. .6 meters. 2. Vivitar 135/.8 there are at least three versions, the other two are 55mm diameter, this is 62mm.
I will not yield a single card more than a thousand. As can easily be confused with two other versions, eBay's sellers are often shot a 30 Jidao on. But you really get 30 Jidao buy, another hand is often the other two versions, usually sell more than a dozen knives. .
(3) 24/2: the best version is Kiron licences, but is rare.
There are also 28 / 2. Kiron launched its own 24 / 2.28 / 2, 28 / 2, the same price and the original Vivitar 24 / 2 is doubled, and yields much less. Kiron generally considered likely to re-improved 24 / 2. .
On the other hand, the Vivitar 28/2 just 28/1. simplified version .9, 24/2 does not have a version of the Series 1, if it really is a KIRO did improve, Kiron version can be seen as Series 1 Edition. The combination of these factors, Kiron 28/2-24/2 to cheap.
24 / 2.28 / 2 seems to have CF version. Vivitar eighties may be sold once, packaging changes, from Nikon-style diamond flower into a flat rubber skin slices Series 1 characters. Head is no longer a constant aperture zoom, but wide-angle extended to 2. .8. Today seems meaningful. .
(4) 450/4. .5 combinations: is the best compromise of one of the head. Have a diameter 10cm aspheric, designed with a 2x, macro function, i.e., 900/9 1: 2.3m .5, working distance. It is said that only 70 only have produced.
Lens superscript MADE IN TAIWAN ROC, but only assembly, parts production for German legend, meet the NASA requirements. The structure and now 2x Vivitar 2x MACRO much like, are added by photomultiplier tubes from the tube. Because it is to fold against the first use, only 2x no aperture coupling, but after all T Mount, with almost no possibility of using other lenses. .
But this only appears in eBay 2x, easily can auction for more than 100 tools. If it has an aperture coupled with bayonet, possibly TC-14C sat than shoulder.
c. . Series 1 in many of the lens by Tokina do, rather than the Series 1 lenses are mainly Kiron production. Copy and re-development of the former is mainly a series, which is mainly 28 / 2,24 / 2. Even if the non-Series 1 products in that year also maintained an excellent system for quality, there are many to meet the professional standards of the first processing. .
The main contribution of the Vivitar is floating lens design, large aperture close-up can have a good picture quality. Therefore the technical advantages of the Vivitar is a large aperture to products of the strongest is a macro and combinations.
From the above parameters can be seen Series 1, Vivitar maximum aperture number possible at that one. .9,3. .8,3,2. .3 Like very conventional settings. .
Therefore, the so-called Series 1 may have design limit, it may be a demarcating jiaoduan, zoom ratio, resolution, and then conclude that the best results. Support for this conjecture is another evidence that many of the Series 1 has parameters similar to the simplified version, specifications and prices are more reasonable, Series 1 more like their big brother the head, leading sign. Develop the purpose of the 1 series is derived from a simple and practical design. The use of materials on the Series 1, coated with VMC. Non-Series 1 Although there is no plastic (except the back cover, Vivitar front cover is metal, inner flocking), but feel to be lighter, it may be more than aluminum. .
By the way: the front cover of the Vivitar is up, if you now use UV ultra thin CPL or just right.
d. . Vivitar 80 in these seven years of optical design has been basically reached the top was the professional head indicators. .
For example, like 28/1. .9 is AF 28/1. .4 completely over just one or two years, 90/2. .5 today continues to be the most useful for macro work, 200/180/3 and 2. .8 par but its 1: 4 close-up also higher than the latter, 90-180/4. .5 20 years AF 70-180-horse, the former extinct for many years, to the extent that the AF B&H 70-180 is called the first macro zoom head. 70-210/3. .5 also in production by the Tamron.
In addition to 70-210/3. .5 Addition, Series 1 on the market are less successful. .
First of all, these lenses provide users considered rare, strange aperture to manual metering result unchanged, so that maximum aperture useless.
Secondly, with today Vivitar mirror of God is different is that Vivitar wild speculations that year, the equivalent of today's buying white price. .
Finally, in the early 1980s, the main factory gate to the advantages of automatic, Vivitar lens design didn't follow the transformation.
On the other hand, Vivitar not in the large aperture zoom to seek further breakthroughs in 80 years although there are 450 products / 4. .5 Hold the line against this jumbo pack, but the overall lead in reducing many have significant weakness. .
Vivitar later are 70-210/3. .5, derived from the prosperous. The most worthy income when it is 90/2. .5, 90-180/4. .5, .5 4.450/. In addition to Nikon, it is the only long short zoom has a macro of the manufacturers. Perhaps what is the relationship between them. But Vivitar and Nikon and Olympus made large aperture should be after the macro Zoomar modernization of three generals.
e. . More rarely into the domestic scene, domestic sales are mostly derived from the simplified version of difference between the performance falls short. .
While the prototype version in a foreign country the majority only in eBay or thoughtful, January saw the half-yearly are also possible. Coupled with the bayonet is diverse, in addition to the AI estuary, mostly obsolete fuselage bayonet F, FD, and so on. On AI mouth users are Vivitar inconvenience is not a problem, and now the camera is organic inner light, AI mouth still compatibility is very good, as for the price, Series 1 except for the big three combinations are only sell 100-200. Non-Series 1-only around 50 knives.
So most people only concerned with AI population, is unlikely to play in the domestic Vivitar. .
Vivitar 1988 to commemorate the 50th anniversary of the production of 50 sets of gilt lens for old clients. In 2000, eBay auction on Adorama in their share of no. 18, asking prices to stop in less than 150 $, no reserve price. Visible now knows that not many people Vivitar. It has become a synonym for the dog's head.
8.80 (70) -200 / 2. .8 (4) resolution of large aperture zoom lens contrast:. .
Finally, you are most concerned about. Here are the authoritative comparative analysis of the results of the evaluation, the conclusion of a more credible and recognized by most people, columns into a table for your reference.
Here to say is: This is just the resolution (in Japan called "Resolving power") contrast, despite the different lens focal length of each segment, image edges and have made a detailed analysis of the central screen, but still no substitute for shooting, can not values in the table "row seating." .
The most obvious example is the Pentax 80-200 f2. .8, its real effect in the upstairs has shot posted, my personal opinion should be the top three in place — but profiling is evaluated, the results cannot be easily changed.
So only benevolent see benevolence and the wise see wisdom - we own to comment on it! . .
80 (70)-200/2. .8 ( 4) large aperture zoom lens resolution comparison chart:.
As can be seen from the table, it is difficult to use words to express the level of the lens resolution. As specific to each lens at different focal lengths, different aperture, the central and the edge of the screen, have a different resolution test results. .
Fans should get familiar with this outcome, a thorough understanding of their own hands, to the fullest at the maximum lens "strengths", avoid using its weaknesses – this is the real purpose of this table.
Summary:. .
Through the above description, at least you can see that in this yingyoumen possess and use most of the focus section, the original lens has unshakable, their quality and manufacturing quality is Vice factory..
The deputy factory is strong in the price is a little sacrifice of performance or life of the time, what comes out of proportion to the substantial price concessions. .
In Vice factory lens, Sigma go to imitated Canon, objectively speaking, I heard the Canon users on this lens ' pay tribute to views than Nikon users (of course Nikon users are also quite good).
Figure Korea is taking the path followed by Nikon, but the relatively heavy and slow AF, bring a lot of grievances, but the image quality Daoshi inevitably say good words; In addition, users of Canon, said that Li-loaded map In the C machine body, "Qi ugly." .
In addition to these two Vice factory, not much else can be explored. William's brother mentioned that Lycra, first of all, is relatively small, would like to know that not many people, followed by the aperture is small, the price is over $ 50 million, is hard to accept ordinary shaoyou was not included in the discussions.
Finally talk about buying "decision":. .
My personal opinion is divided into three segments to consider price: $ 5000, 5000-8000, 8000 above.
The premise that what are you going to pay the price segment, or you quality, weight and price of several key factors determining a first "weighted factors", and should be in 5 years do not "repent" determination. .
Remind that in the course of this principle is — the indiscriminate.
Down would be easier if ask me, I suggest we try to select the original, it must be wrong -. .
Canon with white, light point, cheaper with little white; Nikon's XGP is famous for its great value (here I also posted pictures prove it), if the economy powerful enough to buy the White IS, Nikon new VR G head, has to be seen again, by Convention, Nikon's G-series cameras are high-grade lens;.
Vice-plant the rest of the lens are not to be able to challenge now the point (perhaps only XH can be considered as a "half"), in the focal lengths Ningquewulan not blind "under the capital", and would rather look at it "covert", and never will on, so the money is enough to say. .
To later regret what lots, when 28-200, 75-300, it is best not to think about it — this is my little experience: a great loss to the experience of fever.
Additional information on the latest Nikkor AF-S VR 70-200 f / 2. .8 G IF-ED:. .
And AF-S 80-200/2. .8 compared to more than three AF-S VR lenses, but weight is reduced by 150 grams (1580 vs. 1430). And the Canon 70-200 IS also lighter than 140 grams.
Iris leaves 9, Nikon would like to change the user through the lens focal XGP was poor impression outside the imaging results;. .
ED glass over a period of not less than 5 pieces; tripod ring an attachment, you can quickly make the camera handling; new design of the lens cap is a central bomb.
Spring style can be the case in a hood and easily Abstract, glasses head covered (but how do I look at that cover all the products like the Dragon);. .
The lens is only applicable to the F80, F65, F5, F100, D100, D1 and the fuselage.
