Canon EF-S 17-85mm f/4-5.6 IS USM Review

The first step up Canon's ladder of standard zoom lenses, at least from the kit lens supplied with the 550D and 600D, is the EF-S 17-85mm. It's better built, with a much sturdier feel than the Canon EF-S 18-55mm f/3.5-5.6 IS kit lens for those cameras. Improvements include a metal (rather than plastic) mounting plate for fixing the lens to the camera, a focus distance scale that's tidily positioned beneath a viewing window, ring-type USM autofocus and a non-rotating front element.
