Advantages: Superb wide lens

Disadvantages: NO Image Stabilizer

Since the first APS-C sized imagers appeared in DSLRs a few years ago, photographers have struggled with not having lenses which can provide super-wide angle coverage. With a 1.6X factor, (on Canon DSLRs, at least), a 16mm focal length, like that of Canon's 16-35mm zoom, becomes just 25mm at the wide end.

Recently a number of even wider-angle lenses have become available, and the latest of this batch, at least for owners of the Canon 20D and Rebel, is the recently announced Canon EF-S 10-22mm f/3.5-4.5 USM. This lens is the equivalent on a reduced frame camera of a 16-35mm in full-frame terms.

Keep in mind though that the 10-22mm is an EF-S lens, which means that its designed to only cover the reduced frame size of these cameras. The lens will therefore not work with nor fit on any previous Canon body, though it is likely to fit on all future APS-C sized bodies that have the required lens mount. (The Canon D30, D60 and 10D do not have the new EF-S compatible lens mount flange. They can not be retrofitted, and though there is a kludged solution floating around the net, it can not be recommended, as it endangers the camera's mirror hitting the lens' rear element.)

As for whether this lens is good or not (and as we'll see , it's very good), a buyer needs to decide if an investment in a lens that will not work on a full-frame camera at some point down the road is a good idea

Summary: BUt still considered as phenomenon lens for Canon
