It would appear that the shutter in both my 50mm and 75mm lens is faster than it should be? Is that even possible? I would guess by 3 stops. I am getting BARELY printable negatives with all types of proven (for me) film/developer combinations. I am not sure what else could be wrong. I was thinking electronic shutters, maybe battery problem? I have scoured the net looking for people with similar problems. It is not the meter - I have checked it against my handheld as well as F5.
