price paid:
positive:Great range. Decent speed throughout the range. Very good sharpness. Low weight. Accurate focusing. ACCEPTABLE CA control.
negative:Slow AF, SOME vignetting, distortion at some focus lengths
comment:I use this lens most often when tripping. Apart of superb range it has very decent speed, usually 2/3 EV higher than standard SAL-1870 lens - 4 at 30mm (kit lens 5), 4,5 at 50 mm (kit lens 5,6). This is really sharp lens in standard range - it means that can be as sharp as Zeiss 16-80 lens. Sharpness is good throughout all the range even wide open. AF is so-so on A700 and A200-300, slow on A100, but always very accurate. For architecture photos use 20-22 mm, when there is no distortion - barrel appears under and pincushion over this value, then it reaches good proportion again at 80-250 range. Really good CA control for such a range.

This is ultimate ultrazoom, most useful from all available (maybe for safari shots newest 28-300's are better). Sigma has shown their 18-250 OS HSM recently. I made some tsst shots and quick comparison in same conditions on both Sigma and Tamron today (IX 2009) on A100. Sigma is heavier, has OS built (watch out not to use OS built in and IS). Very similar distortion and CA control but seems to be a bit softer...
