Hi to all.
Today I received Helios 44M (44-3 is on it's way here
) and was astonished by this accidental discovery. Until now, the only 50mm lens that I had was SMC-A 50/1.7 and I did notice that it has "purple problem" when you shoot at night at full aperture. I went this evening to the local market with Helios mounted on K-5 II and was amazed that I couldn't see this problem.
I decided to compare it with SMC-A when I get home and here it is.
Also, with Helios I received the Industar 50-2/3.5, so I included it in the second shoot/test. First test was around twilight and the second one when it was already night.
All lenses were at its full aperture and settings were the same, except, ofcourse, lenses.

P.S. I did notice same "purple problem" (btw, is it the same as PF?) with SMC-A 28/2 @ f2. Is this some kind of common problem with SMC lenses?
