I have had a few cameras but I thought I would try an Om-1. I have a 50mm F1.8 marked "Made in Japan". I was a bit disappointed with the results as it seemed not as sharp as I was expecting, nothing like a contax 50mm F1.7 T* I once owned. The images don't really look sharp anywhere and the out of focus areas when using a larger aperture look a bit unpleasant, not smooth like the Zeiss or another 50mm lens I have, a Canon Fd 50mm on an old AE-1. Have I got a dud lens? I like the little OM-1 so should I just try another lens on it? Maybe I just had a bad day when I took the pics!
