comment:A nice copy with original caps and hoods, and just a bit of white gunk on the rubber grips. This was easily removed with a dry toothbrush.

This lens reminds me a lot of Tamron's later APS-C 17-50 F2.8. They share the same filter thread size, similar number of lens elements, and cover similar focal ranges for their formats. It is slightly larger than the F3.5-4.5 zooms and even a bit larger than the Sigma 28-105 F2.8-4 but considerably smaller than current 24-70 F2.8 zooms. "MADE IN JAPAN"

This copy is not as sharp as my Sony DT 16-50 F2.8 SSM over much of their shared range. It does seems to be mostly sharper than the slower Minolta zooms at the same apertures. It is not very sharp wide-open, especially at the long end. The uneven glow on high contrast edges wide-open probably indicates an alignment issue with this copy. Stopping down to F4 mostly eliminates it.

Overall a very decent fast kit lens for full-frame/film cameras, but not a very useful zoom for APS-C. The Sony version does gain a lot of benefits including in-camera lens compensations and hybrid AF support.
