SteveCampbell Posted July 22, 2018 Share Posted July 22, 2018 1958 Soviet Mir-1 2.8/37 with reversed front glass element in infrared+visible on a full-spectrum 5D mark II I'm pretty sure the MIR-1 is 1958 since it's a 00-prefixed serial number in cyrillic, but perhaps someone more knowledgeable can correct Link to comment
Andrea B. Posted July 22, 2018 Share Posted July 22, 2018 This is way cool..... I don't know whether we have anyone who knows about MIRs or not ?? I think I've seen a website for Russian/Soviet lenses, but don't have a link. I wonder why the 37 mm focal length? Link to comment

I think I've seen a website for Russian/Soviet lenses, but don't have a link. I wonder why the 37 mm focal length? Off the top of my head I believe it was a copy of the 2.8/35mm Zeiss flektagon, using patents that were confiscated from the Germans as war reparations. It's possible that the Russians weren't able to perfectly reengineer the 35mm focal length. Link to comment
Andy Perrin Posted July 22, 2018 Share Posted July 22, 2018 That is a nifty special effect. What is up with the "reversed front element"? Link to comment
SteveCampbell Posted July 22, 2018 Author Share Posted July 22, 2018 That is a nifty special effect. What is up with the "reversed front element"? The front element on the Mir-1 is meniscus-shaped. By inverting it you end up with a concave front surface that causes the peripheral dispersion effect (is there a more precise optical term?) that you see in the photo Link to comment
Andy Perrin Posted July 23, 2018 Share Posted July 23, 2018 Is it a decent lens when the front element is the right way round? Link to comment
SteveCampbell Posted July 23, 2018 Author Share Posted July 23, 2018 Is it a decent lens when the front element is the right way round? Yea, it's quite a sharp lens with a very long throw, and beautiful aesthetics (I have an early metal version). You get a decent subtle swirl bokeh with appropriate focus distance, but not as pronounced as Helios 44/40 or the biotars. Great handling. Link to comment
SteveCampbell Posted July 23, 2018 Author Share Posted July 23, 2018 Is it a decent lens when the front element is the right way round? A quick test showed that it's not very useful in UV however... Link to comment
Dmitry Posted July 23, 2018 Share Posted July 23, 2018 Recent test of this lens made in 1985. There are better lenses exist for sure. But it may have limited use in UV. Link to comment
