I've acquired on old f/8 coated Super Angulon in a Compur 00 shutter, which I've had cleaned so that it functions well. I've shot a couple of sheets of film wit h the lens and I must say that I am dismayed at edge sharpness (I've shot at f/2 2 and f/32.) Center sharpness seems OK, but toward the edge of the field (not th e image circle--the 4x5 field with no shifts or rises) there is a loss of defini tion. Does this match the experience of others. Has anyone tested one of these f or maximum sharpness and definition at a variety of f/stops? This is an old wide angle design, and the edge to edge sharpness you might find on, say, a 24mm Nik kor meant for 35mm, doesn't seem to be there.
