comment:A very clean copy with original caps and hood purchase from a large eBay retailer. This lens looks like a 9/10ths version of the Minolta AF 100 F2.8 Macro RS. The front extension works very similarly. "JAPAN"

I was expecting good performance, but it performed very well. It has much less lateral CA than the Minolta RS Macros, the 60mm F2, or the 85 F2.8. It does have more longitudinal CA than the Minoltas. The focus also drifts just like my copy of the Minolta AF 100 F2.8 RS. It is sharper at F2.5 than that lens at F2.8.

Something metallic is rattling inside it--maybe related to the focus shifting issue. The aperture blades are flipped from the typical orientation.

Overall a very good 1:2 macro/portrait prime.
