comment:The original retail price was $700 when released in 2007 and is now $1000. My first used copy looked very nice and came with the hood and both caps purchased on eBay. After selling this copy I purchased a second older copy that had a locked focus ring and wouldn't auto focus to the minimum distance. I then bought a factory refurbished copy from Secondipity. "JAPAN"

It is slightly faster optically than the other variable aperture DT normal zooms but slower than the full-frame normal zooms. It reports f/3.5 at 18 mm unlike the 16-105. A maximum aperture of f/4 at the long end would have been nice.

This lens performs similarly to the other APS-C normal zooms with good center sharpness wide-open and variable corner performance with a good deal of distortion at both ends. It's best image quality is at 35 mm which is good for an APS-C lens. It is a bit better at 35 mm than the 35 F1.8. However, the corners are quite soft around 20 mm and also a bit soft around 50 mm. The 18-55 kit has much less focus plane curvature at the wide end. The 16-105 is also slightly better on the wide end. It has much better center sharpness and contrast wide-open than the Minolta zooms.

The Sony DT 16-50mm F2.8 SSM is definitely the better zoom, especially if you prefer wider angles-of-view. But this is a very nice kit.

Test chart comparison with Tamron 17-50 F2.8 and Sony DT 18-135 SAM.
