Zorki, thank you. Looks as though I shoved my big foot in my mouth. I've learned a bit from you and I guess that's the good part of making a mistake if you let yourself learn. I just wish the Zenit site had some english. I can spell out a little Russian but not enough thati it makes sense to me. I did bookmark those pages and will be going back to them. Maybe I can get my nephew to read the zenit page to me.

Thank you for the correction.
I was convinced, as well as many other people here (in AR) that Industars are Elmar copies. Physicasl similarities help to think that way.
Thinking in a simple way, it would be logical if the russians "borrowed" some basic design from Leitz, why no to do the same with lenses?.
But from a practical point of view (and they were), having all the Zeiss info and tooling at hand, they simply placed the lens in a different barrel/mount.

Russar is named after Mr. Rusinov, who invented that particular optical design.
Korsar name is considered an insider joke by Arsenal engineers. At the time of its introduction in 1980s Mr. Korsakov was the chief bureaucrat in Soviet optical industry.

I guess alot of people are fooled into thinking Industars are direct Elmar copies because the collapsable ones look so much like 50mm Elmars.

Hello,
the Orion-15 is a copy from the post war 4/25mm (sic!) CZJ Topogon. Both have a symmetric design with 4 elements.
The prewar 4,5/28mm FED lens has got 6 elements (regarding to Princelle). I guess it is a copy of the Leitz 6,3/28 Hektor.

Andreas,
It doesn't sound like those lenses are exact copies. The f/stops are too different. Didn't Leitz produce a prewar 28/4.5 in very limited numbers?

Hello Vince,
the f/stops are not similar and the focal lenght isn't, too. However the Orion-15 is a Topogon copy - you just have to compare the lens design, it is almost exactly the same. The Orion-15 ist slower and has another focal lenght, because in this way it was far easier and cheaper to produce.
Regards,

Tair also has cosmic connections. It's named after the star Altair. Al is just an article in Arabian so it's like Al-TAIR.ZorkiKat said:

Orion 15 it is derived from the Topogon, but it has a "limited" aperture blade: even at full stop, the diaphragm is not completely open, but the blades can be clearly seen. The reason is to limit vignetting.arothaus said:
I don't know if original Zeiss Topogon was built in the same way, but surely Russian had a common feelings to not barely copy the german lens, but try to improve them.
FED-35 (28mm f/4.5) is an original russian design, since it was built before the WWII and at that time nor Zeiss than Leica had a similar lens in production.
It has six glasses, all air-spaced without coating, simmetrical design.
Russar MR2 is a russian project too, where MR stands for Michael Roosinov, who invented that scheme. Six elements in four groups, simmetrical design.
Industars are pure Tessar design, f/3.5 resemble the look of the collapsible Elmars, but the most advanced version, f/2.8, has its own look. Industar 61 has lanthanum glasses.
Jupiters are all Zeiss Sonnar clone, except the Jupiter 12 which is a copy of the pre-war Biogon. Interestingly, the Jupiter 3 was originally a clone of the Zeiss Sonnar 50/1.5 but it was slightly modified soon after its introduction, and it was further improved in the prototype named Orchideja 3
There is another prototype lens, the Sputnik 4, which was no more than the clone of the Biogon 21mm. It was dropped since russians had already the Russar

Zenitars are a model, like Industars. I recall they are made by KMZ and I believe they are all-Russian design

Maksutov was the designer of the Maksutov telescope. The Maksutov Cassegrain is a *******ised hybrid that is cheaper to make. I believe the American Questar is a genuine Maksutov. Most others are Russian. The M in MTO is for Maksutov being - Maksutov Tele Optik. I believe Maksutov had a manufacturing facility and the early version of the MTO 1100mm was made there. My Maksutov is made by Lytkarino.
I believe the Rubinar looks like a kosher Maksutov but isn't. It's a Maksutov Cassegrain, which explains its low price. It is also a very good lens.

In fact, Tair is the name of lake near resort where Mr. Makustov (another notable Soviet optical engineer) was taking vacation. According to folklore, he got the glimpse of that lens' optical design from observing the reflections on surface of lake Tair.iliks said:

Some early lenses were exact copies but later the basic designs were in many cases improved upon. For example the Industar-50 and Industar-61 are better than any pre-war or WW2 German four element Tessar type lenses; assuming good examples of course. The Industar-61 is so good that I doubt the 1970's Carl Zeiss Tessar 45/2.8 for the Y/C mount is significantly better. Haven't seen any measurements though.VinceC said:

you are on to something here,
I always found that the I-22 gave me results that are very close to my post war 50mm Elmar.
more so than the I-50 and the I-61 L/d.

That's a bit outside of lens design: The voskhod camera was named after a rocket.
And it's interesting but I read not so long ago the memories of a German rocket engineer who worked for the Soviets. They were only allowed to make the planning and were strictly confined in a special camp, their results were taken by the Russian engineers for evaluation and on rare occasions the German chief sceintist was called. So they had not germans doing the work for them, but did very much themselves. Whereas the first Soviet Jetfigher is said to be built strictly following German plans Sorry if it got to OT....

-`Voskhod` is not rocket - it is spaceship... same difference as between `Apollo`spaceship (okay - Mercury, to be in same league with Voskhod) and Saturn rocket
- First Soviet Jet Fighters built in big series: MiG-9 and Yak-15 had German jet engines copies. Other costruction was of Soviet design. Yak-15 for instanse was classic Yak-3 with jet engine replacement.

The head of Russian rocket and space program was Sergei Korolev. He grabbed all the Germans that America missed.
Very bright man, was a political prisoner but was sent to Germany to grab rocket technology and eventually masterminded Soviet space program.

Voskhod simply means "sunrise". The metaphor is obvious: something red and brilliant coming up in the East - the same reason why there is a camera called "Zarya" ("Dawn"), which by the way is also a generic brandname applied to all sorts of things, from cameras over the central module of the International Space Station to watches and collective farms - a colleague of mine in Uzbekistan worked on a collective cotton farm called "Qizil Tong" ("Red Dawn") in Uzbek and "Krasnaya Zarya" in Russian.Spider67 said:
Voskhod was sort of a generic brandname in the Soviet Union. The most famous ones are the spacecraft and rocket, but there were also motorcycles, radio tubes and the camera named Voskhod. Even today there is a steel mill in Krivoi Rog in Ukraine and an firm producing sensors and actuators in Pavlovo in Russia called "Voskhod". The camera came out in the same year as the Voskhod-1 flight, the motorcycle the following year. I don't think that these were "named after" the space programme (otherwise there would have been regular brands named Gagarin as well, instead of just occasional commemorative editions of something else). I rather think that the Soviets wanted to install a powerful domestic brand associated with progress of Communism, and that they took the opportunity of starting the brandname in 1964 with a powerful association of symbolic value, namely the spaceflights. Finding out how this really worked is part of my mad project on photography in the Soviet Union.
Space associations are incredibly powerful to this day. You'd be hard pressed to find somebody in West Germany who knows the name of the first West German in space (the first East German, who was actually the first German all in all, is easier because he starred in a very popular film recently). However, 20-year-olds in Uzbekistan know who Leonov was (not to speak of Gagarin). I met several people in Tashkent in their 40s named Valentina Vladimirovna and when I asked others about where this concentration of Valentina Vladimirovnas came from, everybody immediately said that this was because of Tereshkova in 1963. In 2002 I took a series of propaganda-style photographs called "Welcome to the Soviet Union" showing amongst other things the rocket and the Sputnik memorial at the VDNKh park in Moscow; I gave the series to a friend in Smolensk (who was ten when the Soviet Union collapsed!), and she wrote me a very touching letter afterwards saying "they give me a feeling of pride that never leaves me now". I think this association and pride is actually stronger in the ex-USSR than the American pride with having been to the moon first.
