I just got myself a used Praktica with a Pentacon auto 1.8/50 multi-coated
lens. I haven't taken any pictures with it yet, but I noticed that the
diaphragm blades on the lens are much more glossy than on my other lenses.
I assume that will affect contrast, especially at medium and small
apertures, as light reflected from the film will be reflected back by the
diaphragm blades.


A very late answer.
I have both a 55mm f1.8 Super-Takumar and a similar spec 50mm Pentacon.
I use use the Super-Takumar as a manual lens on a 20D.
The super-Takumar images are perceptibly yellow, nothing that can't be
corrected,
but its contrast and resolution are noticable better than the pentacon.
I hope this helps
