I have five 50mm M39 lenses from the former soviet union and thought why not do a comparison. So i took my Zorki and did ten shots of the same subject, just switching lenses in between. The first round is all lenses at f5.6 and the second round i all lenses as wide open as possible.
On a side note i might need to adjust the rangefinder on the old Zorki a bit as i was actually focusing on the eye of that little fish in the picture but focus seemes to have landed on the corner of the amp underneath the fish. So it is off by about 20cm or so. I was at around 1,2m distance to the subject.
The lenses are lined up in the pictures and from left to right: Industar-61 f2.8, Jupiter-8 f2, Industar-22 f3.5, Industar-22 f.3.5 (heavily used condition) and Fed-10 f3.5. All lenses except the heavily used industar are in very good condition.
I wish the Fed-10 was as sharp as the industar-22, but it just is not. It is probably in even better condition than the industar. When shining a light into it i can see that the fed-10 is just very, very lightly coated compared to the thick blue/purple layer in the industar. At f5.6 they seem equal, but at f3.5 the Fed does not come close.
I am still using the fed-10 a lot, because it is just that tiny bit smaller and fits better in the pocket. Also my Leica lens cap holds tighter on the fed-10. I wonder if i could find a copy that comes closer to the industar in terms of sharpness at f3.5
Industar-61 as expected super sharp but the Jupiter-8 does not need to hide. In fact i was surprised that the script near the inputs of the Monacor reverb unit is slightly sharper on the Jupiter than on the Indu61. I'd certainly prefer the Jupiter over the Indu because it goes to f2, seem to be a bit lighter and is a just hint shorter.
The heavil used industar-22 copy has been cleaned, is free of haze or fungus but has lots and lots of micro scratches.
I might do a colour comparison the next time i find colour film for a bargain.
