Thx! This time I focused at 4 m and the result was great:
This made me very happy:) Great moderate flares, not too much.
I do have a Helios 44-2, at least thats what it says on the lens, or is there some other version? That Dog Schidt lens look good, wonder how flares with the Isco look on that thing. That redstan clamp looks great, but expensive so I will first try a DIY. Any recommendation for an affordable diopter?
