I've recently bought a Zorki 4 and the results I get from my test roll are quite disappointing. I've been calibrating the mirror, adjusting it for both infinity focus and close one (1 meter). Here is the result I get for a picture taken with the focus set to infinity on the lens. As you see, the picture is blurred and it seems that only the close part of it is quite neat (bottom of the pic).
Would anyone have any explanation for that and how to fix it? I don't really get how this is possible as even if the calibration setting was not accurate, it would be some close distance pictures that would be blurred (which is not the case).
Thanks for your help
