Summary: It is a practical zoom lens, almost standard for my 300D.It covers 32-56mm of a 35mm standard. The USM focusing on the 20-35mm is silent and fast. It is sharp and a very good replacement for my previous kit lens.

Summary: Canon EF 20-35mm f/3.5 - 4.5 USM Wide Angle Zoom Lens for Canon SLR Cameras. Easy to use,very sharp pictures, it is a strong lens, good autofocus system, the luminosity is really good. It's a light weight lens, not heavy.
Summary: This is a wonderful lens. It is especially nice for travel photos in cities, indoors, and for some landscapes. You also need to get a hood because of the wide angle of view. In addition, you need a filter to protect the lens as well as function as a filter -haze or polarizer. The filter must be a special wide angle filter (thin metal ring) and you won't be able to attach the lens cap over the filter. Small price to pay, however.
Summary: This lens is good for those who are looking to get decent wide angle but don't have the budget for the EF 17-40 f/4L. In order to beat the quality of this lens you need to spend almost double. I used the 20-35 on my Rebel XT which makes it equivalent to 32 to 56mm. It's not as wide as the EF-S 18-55 that came with the camera but the quality is much better. The ring type USM focuses fast and quietly. Overall, a great value for the price.
