The camera in question is an old Konica TC Autoreflex. Any shutter speed faster than 1/60 is off by about 2 stops, and gets progressively worse the faster the shutter speed (the fastest is 1/1000). I calculated appx shutter speed times using this app w/o the the phototransistor plug.
Does anyone here have any experience with adjusting physical shutter speeds? Do I need anything else other than a steady hand and a small screw driver? I will say that I've never opened up a camera before, but I really don't have anything to lose her except a couple of hours. The camera was gifted to me, and it came with a really beautiful f/1.4 prime lens in pristine condition.
