Legacy glass newbie here. I've been using an adapter w/ my Konica Hexanon AR 50mm f1.7 w/ great results. I wanted to try out the Minolta Rokkor 45mm pancake. Found a local on CL who sold me the lens and body for $30. I thought it was the same as the Konica. Are the AR and MD/MC mounts really that different? (Yeah, I know, I tried the lens and it didn't fit. But at $30, it was a steal w/ the body.) Has anyone compared these 2? I know the image threads but was looking to see if 1 was better than the other.
