I'm starting to fall in love with legacy minolta lenses. In the last week, I've acquired 50mm 1.4, 50mm 1.7 (which I will probably sell since I got the 1.4), 35-70mm 3.5 macro zoom, 135mm 3.5 and Vivitar 135mm 2.8 (both 135mm's were picked up today at salvation army for $15!!!). I've read that most people use aperture priority with auto-ISO...and let the camera pick the shutter speed. But since the camera doesn't know what the focal length is, will it pick the "correct" shutter speed? I've read that the min shutter speed should be 1/focal length. When I was testing out the 135mm, the shutter speed varied between 1/30-1/60 (if I recall correctly). SO i tried shutter priority and set it to > 1/focal length...but them the preview gets really dark. I suppose at this point i could jack up the ISO? And in shutter priority, I understand that the camera sets the appropriate aperture? But since aperture is set on the lens, is will the camera just go with the set aperture? I also tried shooting in Iauto...and I seemed to get the best results using this mode. I'm scared to try full manual mode...as I am VERY new to non point and shoot cameras so I want to "ease in" so to speak.
