comment:This was a nice clean copy in the original box. The Konica Minolta DT version had a list price of $500 when released in 2005. Sony and Tamron have discontinued their versions of this lens. Sony replaced this lens with the longer 18-250 and the shorter 18-135 SAM. Tamron has a new $200 18-200 that includes a focus motor. "JAPAN"

This lens has similar problems as the 16-105 but with even more distortion on the short end and less sharpness at the long end. It is one of the better performing lenses at 24 mm--a focal length that is unmarked on the zoom scale. However even the little 18-55 SAM II performs better at 18 mm and from 35-55 mm. It does seem to perform better than the older 18-70 kit zoom.

Despite its stated focal length range this lens is not equivalent in range to a combination of the 18-55 + 55-200 SAM lenses. At close focus is not much longer than the DT 18-135 SAM. This copy performs poorly beyond 70 mm. The 16-105 might even have more reach as far as ability to resolve detail. The 55-200 SAM performs much better than any of these along with having considerably more telephoto reach.
