comment:This is now my standard "take anywhere" lens. It's light, has reasonably responsive auto-focus, and was surprisingly sharp.
It feels well-made and solid, and looks great with the petal hood. I really like the versatility, and the fact that you can get close and get a pretty sharp macro at 100-200mm I have gotten it to auto-focus as close as 14 inches (350mm) at wide angle, which is closer than specifications. It hunts for focus some in lower light.
In my test-card shots on an Alpha 700, it was as sharp as my 105mm Sigma macro in parts of the range. At the long end, it has some color fringing. Another "defect" was some barrel distortion between 28-40mm. This was only noticeable when taking shots of rectangular objects that fill most of the frame.
It is still available new, but no longer in the Sigma lineup, and at $109 new on eBay, my best value ever on a lens. If you get a chance, pick one up.
There is a good review here:
