|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. 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 APS-C 50's. The field-of-view is just slightly wider than the long end of the 18-55 SAM II.
This lens is sharper than the old MD 50 F3.5. As far as I know there is no matched extension for 1:1 like there was for MD lens. The 50 F2.8 RS has much more CA even stopped down.
