The EF-S 10-22mm f/3.5-4.5 ultra wide angle zoom lens fills a gap in Canon’s product lineup. It is marketed at consumer grade users looking to add ultra wide angle shooting capabilities to their photography kit. The EF-S mount of the 10-22mm works only with the EOS 20D, 30D, 40D, 50D and Digital Rebel bodies.
As far as optical quality, Canon included 3 aspherical elements and one super-UD element to this lens to increase image quality and sharpness despite the ultra wide focal lengths the lens covers. Autofocus with the 10-22 is quick and precise. Additionally, the lens allows users to focus as close at 9.5 inches from a subject. The 10-22mm f/3.5-4.5 is designed for a very small range of applications where ultra wide angles are necessary.
Interesting results occur when the lens is used for other applications. When used for portraits, for instance, resulting images are dramatic and creative looking as they distort body proportions to unrealistic size and shape. For most photographers ultra wide angle zoom lenses such as this one make a good 3rd or 4th lens choice. It would be best to cover basic lens choices before purchasing this lens.

What Users Like About This Lens
Autofocus on the 10-22mm f/3.5-4.5 ultra wide angle zoom lens is very fast and reliable. Users also tout the capabilities to the depth of field on this lens. It is very deep and resultantly produces images with great detail throughout. The build quality of this lens is solid, it is light weight and very small, making it an easy lens to carry on the camera or in a camera bag.
What Users Don’t Like About This Lens
Considering that this lens is designed for EF-S mounts and therefore consumer grade camera bodies, it is rather expensive. Additionally, image quality suffers as a result of the ultra wide focal lengths covered. Chromatic Aberration (a result that denotes poor image quality) occurs in the corners of most images. Images are also not as sharp as the results from non-wide angle zooms or similar consumer quality.
This is not necessarily a bad thing for some users, as although image quality is not the best with the 10-22, details are a lot smaller due to the wide focal length. Finally, when the aperture is wide open strong vignetting occurs in the corners of images. Vignetting is similarly apparent throughout the aperture range of the lens.
