My go to 50 is an odd, but extremely (razor) sharp, Canon 50mm f/2.5 compact macro. Sadly, it is no longer made. AF is slow and loud and prone to repeatedly hunting and missing focus but the images it makes, particularly portraits, are really good. On full-frame, it does have some loss of sharpness at the edges but on a 1.6 crop sensor camera it is simply great.
