Hi there. I just bought a nice Contax 137MA camera along witha very nice Planar 1.7. Problem is the ASA dial will not move past ASA 400. What could that be? Any ideas, suggestions, please? And yes, I lift the outer ring before turning it, but it will not move beyond the mark just before 400 ASA, no matter how hard I try. According to this cameras specs, it supports speeds from 12 to 3200 ASA.
I bought this camera to shoot 800 ASA film, so I am stuck...

Thanks a lot!

I would first set the ASA at whatever value you want and compare the metering of the camera with a known good light meter or other camera. If it agrees, then the parts under your rewind knob have probably not been scrambled by someone else. In that case, you can set the camera at ASA 400 and simply use the exposure compensation part of the same dial get an effectual ASA 800 setting. If not, check back as you will be doing some exploratory surgery to diagnose and (hopefully) correct the problem.
