I recently received a lot about how to purchase and use of Zeiss. .
Jena lenses, here I do answer these questions.
First, the added point of history. .
After World War II, is located in the Zeiss Jena company is Russia's control of the (German post-war is split in four countries of the victory of the Russian part of East Germany, the United States to France and the three countries part designated as the Federal Republic of Germany) of the Zeiss company many scientists in the US's help, they fled to West Germany in Oberkochen established a new factory, where production in many products, including the top camera lens. The original Zeiss company's remaining personnel and production equipment and design samples are pulled to the Ukraine, where he established a new camera factory to produce a series of follow the Zeiss lens design of the Soviet Union.
In the communist world, Zeiss Jena optics brand is called "Carl Zeiss..
Jena and use traditional lens design, including Sonner, Biometar, Flektoon. Zeiss in different countries in the West.
Jena optics brand called different, are not allowed in the United States called "Zeiss", sold in the United States, products are labeled jenoptik telescope trademark and lens products were labeled aus. .
jena 。 Zeiss Oberkochen also is allowed to use the lens series product name, sonner hereinafter referred to as "s" is short for "Biometar Bm".
, Flektogon is referred to as "f" (Flektogon Is this standard can not remember exactly). Britain and some European countries allow the use of carl zeiss. .
Jena trademark, but still use the abbreviated product line name. In some other places, and communism as a trademark in the world (the Communist world, Oberkochen not using the Zeiss "trademark, they start with opton trademark, which is why late 1940s Rolleiflexes Assembly is opton brand lens).
Therefore, "carl zeiss jena sonner" also called "Carl Zeiss Jena s" or "aus Jena..
S "is exactly the same lens, there is no quality difference between the purchased time to care.
Zeiss Jena Sonnar and Zeiss Oberkochen Sonnar have the same structure, exciting is that they are almost the same quality,. .
Flektogon and Distagon is also true, but there is a little Biometar is altered by the Tessar evolved double-gauss structure lens.
If you do not remember correctly, Carl Zeiss Jena probably sometime in the 60's into the VEB Pentacon, VEB. .
Pentacon also owns Ihagee (pre-war Exakta) factories and production plants, Pentacon Praktica cameras, Zeiss.
Jena Praktica mainly produce lenses, and the same clan brothers Oberkochen use Schott glass. .
Zeiss Jena lens product shape there are four basic version. The first version is white (aluminum primaries) version, mostly in focus ring has a leather-clad, 1956.
To 1963 with the manufacturing, all single-layer coating; second version of the whole body in black, focus ring with black plastic cladding protruding particles, 1961. .
Until 1963, single-layer coating; the third version is called the "zebra", 1963.
To mass production between 1967, aperture control ring on a black and white decoration, is also single-layer coating. .
The Fourth Edition is a butterfly in black, red and black plating (two I have). 1967-1978 between the products of a single film, 1978-probably.
1990 for the multi-layer coating products. Multi-layer coating of the Zeiss. .
Jena lenses very few exceptions to the "MC" tag. Black "MC" lens has a mechanical switch to convert the automatic aperture and manual aperture, so that you can easily get what you want aperture value, AF, switch back to the manual block, see the exposure value (or let the camera do it), press the shutter. The latest version in order to cope with Praktica.
EE camera to increase the electronic contacts, but that was not much use for us to buy when you can not to worry. .
Therefore, it is most worthy of purchase of the entire body is black and "MC" tag of the lens, there are no electronic contact points are available, but do not care if the trademark is "aus Jena" or "Carl.
Zeiss Jena ", marked" Sonnar "or" s ", because that is the same product..
Zeiss Jena lenses there are two main entrance (there are some old lens use CONTAX rangefinder bayonet, that does not include), Pentacon bayonet and M42.
6 bayonet. The Zeiss Jena VEB Pentacon mount was used. Pentacon 6 is a mid-lens cameras, Exakta. .
66 (presumably in 1992 were sold to Schneider, and has been producing of 1999), the predecessor of the manufacture of lenses spread Flektogons 50mm.
And 65mm, Biometars 80mm and 120mm, Sonnars 180mm and 300mm, in addition to Flek 50mm and. .
Sonnar 300mm is f/4 is other than f/2. .8. 65mm lens without black MC version.
Zeiss Jena as well as the 35mm Pentacon lens camera manufacturers, but most are marked "Praktica" trademark, including 35mm. .
Flektogon and 135mm Sonnar. Longer Sonner M42 lens is in place, and the bayonet 180mm is often marked "Olympia.
Sonnar ", but this usually appears in the old lens. Perhaps some other I do not know - I focus on the home field of the lens..
Both of these tabs can be very easy to get to go with the Canon community circle.
EF mount camera, you can buy these from DVDTechnik up lap, the website link below:. .
http://www。.dvdtechnik。.com/other/adapters/adapters。.htm。.
M42/EOS up lap 18 U.S. dollars, Pentacon. .
Circle Six/EOS 35 dollars received. I have received a circle are bought from there, they have a good faith. (They also sell other interesting then ring, such as the NIKON manual head and EOS camera add-in). All circles are non-electronic, all you have to manual focus, manually set the aperture value, Aperture priority, the module can realize normal work.
Incidentally, M42 mount Pentacon first was used in the early 50s. In order to cater to the market while a large number of PENTAX lenses have also used this bayonet and making noise, so that the public has the "Pentax..
Screw gate "and" universal screw gate ", which in fact is one thing.
Overall, DVDTechnik buy up lap, from ebay to buy Zeiss Jena lenses, with "Jena" keyword search when aus Jena. .
Brand and Carl Zeiss.
Jena brand series of lenses will be caught, but also seized a number of telescopes and microscopes, so you can use the "camera lens" keyword filtering, I feel that this search is still full of fun. .
Some of Germany's ex-Praktica lens camera manufacturing companies were incorporated into the VEB Pentacon, where interesting one is Meyer.
Gorlitz, they produce can be customized to replace the 300mm and 500mm mount binoculars, only a 500 / 5. .6 Pentacon Prakticar. .
MC lens worth having, multilayer coating, very strong, very large and very heavy. Coupled with a strong monopod you will be able to shoot games, if someone dares to laugh at you, you can use this lens to interrupt his leg, HA HA. Ebay on the two cards are of the mouth.
Listed below is a promising lens:. .
35mm/2。.4 MC Flektogon (or "f")。.
135mm / 3. .5 MC Sonnar (or "s"). .
180mm/2。.8 MC Sonnar (or "s")。.
300mm / 4 MC Sonnar (or "s"). .
500mm/5。.6 Pentacon Prakticar MC。.
The first four of the trademark Carl Zeiss Jena or aus Jena. .
