Sigma 10-20mm f/4-5.6 EX DC HSM Lens for Nikon Digital SLR Cameras
Customer Reviews

there are currently 4 wide angle zoom choices available on the EF-S canon mount (d-rebel/xt/20d) canon 10-22, Sigma 12-24, sigma 10-20, tokina 12-24. Of these, sigma 12-24 is the only one which is usuable on a full frame sensor (canon 1d, 5d, possible future cameras). There is sizable difference in field of view between the 10 mm, and 12 mm. and the tokina is closer to 13 mm on its wide end. The sigma retails for about 2/3 the price of the canon. Optically they are very similar, with the canon having a larger maximum aperature, which is generally not important in a wide angle lens. The built construction is EX, they higher line of sigma, and it excellent. The focus motor is HSM, making it fast, and very accurate. Resolution chart show the sharpness to be very close to that of canon. The color and contrast is excellent, the flare and chromatic abberation genenrally well controlled. A fun lens to use, and excellent value....By best value wide angle.
