comment:The original AF version of this lens was $350 in 1985. This version was $300 when released in 1993. Minolta added a focus hold button and a range limiter switch to this version along with a more circular aperture. Cosmetically it matches the other RS series lenses especially the 100 mm Macro. Sony's list price for their current version of this lens is $600. This is a nice clean copy with original caps purchased from an individual eBay seller. "JAPAN"

This lens extends almost as much as the 100 mm macro at 1:1. The focus scale looks to be nearly identical to the 50 F3.5. The amount of grip rotation and barrel extension at 1:2 is very similar to the smaller lens. The optical elements are barely any larger. The front elements of both are deeply inset.

This lens performs similarly to the less expensive F3.5. It has a slightly warmer color cast unlike the F3.5. It has relatively high amount of chromatic aberration. Sharpness and CA might be down to sample variation. It is much sharper than my 100 F2.8 RS.
