comment:I purchased two of these a couple of years apart. The first wasn't very sharp, but I liked the rendering. I cleaned some crud off of the front element of the second copy. This lens was $200 when released in 1994 just over $100 cheaper than the 50/2.8. Cosmetically it matches the other RS series lenses. Supposedly it uses a different optical formula (5/5 vs 6/4) than the older, manual focus Minolta 50mm F3.5 1:2 Macro lenses dating from 1961. This is the simplest A-mount lens in terms of actual parts. "JAPAN"

The larger body is used to accommodate a deep fixed hood. The working distance is fairly large because of the fairly low 1:2 maximum reproduction ratio.

The field-of-view is slightly narrower than the faster Minolta 50's and significantly narrower than the 50 F1.8s at the same focus distances. The field-of-view is just slightly wider than the long end of the 18-55 SAM II.

It is really hard to tell which 50 mm lens is the sharpest even after adding a 2X teleconverter to an APS-C camera. This lens definitely works the best on a Kenko MC7 teleconverter--very sharp to the extreme corners wide-open. The 50 F1.4 and 50 F2.8 just have much more CA even stopped down.
