comment:A new looking black copy with original retail box and paperwork purchased from a smaller eBay store. About a month previously I had sold my last Sony DT 50 F1.8 SAM. The SAM lens seemed redundant after purchasing a Minolta AF 50 F1.4. This lens is currently and frequently on sale for $250, but the normal retail list price is $300. On APS-C it acts like a 77mm F2.8 lens on full-frame. "Made in CHINA"

This is a fairly substantial lens. It is significantly larger than the all manual Fotasy. It is about the same size as an Minolta MD 50 F2 or F1.7 with adapter and a bit larger than the Sigma 60 F2.8 Art. It is interesting that it has more lens elements than the FE Carl Zeiss 55 F1.8.

This copy is quite sharp wide-open. It is pretty close to perfect across the frame. It has a bit more chromatic aberrations than the Sigma 60 F2.8 Art, but much less than the Minolta AF 50 F1.4 or Sony DT 50 F1.8 SAM. The corners are much brighter than the other APS-C lenses.

As noted in other reviews below, contrast-based autofocus on the A5000 is a bit erratic with this lens (as with the Sigma 60 F2.8 Art) probably caused by the shallow depth-of-field. I plan to eventually upgrade to a body with phase-detect sensors.

Overall an excellent, fairly inexpensive, stabilized, somewhat fast 50 mm lens for APS-C. A faster legacy 50 mm lens might be cheaper, but it will not be as useful.
