5.0 out of 5 stars best value wide angle., February 9, 2006
This review is from: Sigma 10-20mm f/4-5.6 EX DC HSM Lens for Canon Digital SLR Cameras (Camera)
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.

So are you saying the 5d with the 12 (from the 12-24) is much better than the 10 with the Rebels (which becomes 16mm)?

Hello,
Is there some sort of adapter than can make the sigma 10-20 mm fit into Canon Rebel?

Can this lens be used on Canon 7D?

This lens will mount on any canon ef and efs mount camera. on the canon aps-c cameras, which are the entire rebel line (xxxd) the entire xxd (10d-60d) and 7D, it works through the entire focal length, and at 10mm would give you the same angle of view as any other lens at 10mm on the same camera. My original review is old. I would now go for the much better tokina 11-16 2.8, or the sigma 8-16, though both are more expensive. Also, the Canon 10-22 seem to have less sample variation, although it remains more expensive.
the lens can also be mounted on the aps-H (1d-1dIV) and well as full frame cameras, but the image would not fill the frame, especially at the wider end, and would certainly not be considered appropriate for the full frame camera.

Raver, your idea that the EF-S lenses work differently than the EF lenses on crop bodies is 100% wrong. The Canon 10-22 EF-S provides exactly the same view on a crop body that a Canon EF 16-35 would on a full-frame camera.

Samuel A says:
Again, the EF-S does indeed mean that it will mount on only APS-C bodies and not on Full-Frame ones. However, unlike what Raver wrote, the 1.6x crop factor DOES apply, as David mentioned, so the EF-S 10-22 does NOT give you a true 10-22 but rather begins at 16 mm (10*1.6=16) and goes to about 35 mm because the smaller sensor size causes that additional 1.6x to be lost.

So there is no benefit in purchasing a Canon lens to overcome the 1.6x limitation as the Canon lenses are subject to the same restriction.
