View Full Version : 35mm f2 summicron V1 M2 has 0.65m focus = Fake?
I seen a 35/2 v1 without goggle, 2'2" / 0.65m focus. Is it possible to be a original one or mostly fake?
My V1 Summicron (#1654xxx) does focus to 24" (0.7 meters). Yours could be a conversion from a "goggled" version. Just check that it stays in focus across the whole range -if it does - just use it.
For a while it was a popular conversion as the M3 Goggles made the lens clumsy - as well as adding extra glass in front of the finder. Most conversions early on were made by competent technicians who reset cams and had them checked out on collimators.
Just put the camera/lens on a tripod - shoot a roll at 0.65/07/1m/2m/3m/5m and infinity and check for focus shift or focus "failures" Try to do it at F2 first and use the rest of the roll for "shots" at varying apertures and check again.
This is the kind of test I do with every lens at some time.
thank you for replying, I will test it on M9 before use in on my M2.
You may wish to check the lens again quickly, a few shots, on the M2. It's possible that the two rangefinders don't match exactly.
If it is a conversion from gogglised, then there may be evidence of the original boss which was used to retain the goggles.
