Sigma 10-20mm f/4-5.6 EX DC HSM

First off the focal length of this lens is great. The build quality is quite good, I really like the stiff feel of the focus and zoom rings. It would be nice if the focus ring was even stiffer though, in my opinion. This lens is fairly heavy, though not too big. The weight gives great handling but makes it a bit for cumbersome to carry around

Optically this lens is capable of good, but not incredible images. Stopped down to f/11 it is good enough, but the corners are not stellar. According to review it has some weird uncorrectable distortion at 10 mm. I haven't shot any images to test this so I can't confirm or deny that.

The two biggest advantages of this lens in my opinion are focal length (10 mm is great) and price (this lens is the cheapest APS-C super wideangle).
