Ara, I realize that there's probably no grass in the upper corners of the frame. But is whatever is there darker in the corners too?Quote:

Dave, the cutoff isn't due to the diaphragm, its due to a field stop (shouldn't be one in a 50/1.4 Nikkor, but there is one in the 75/4 Apo Rodagon D 1:1) or some other mechanical obstruction, usually at the front of the lens or to the lens' design (the 38 Biogon with which I took my example shot). I hang a number of lenses in front of a #1 on my little Graphics, always worry that the shutter's barrel will block the peripheral rays.
