Verified Purchase(What is this?)
This review is from: Canon EF-S 10-22mm f/3.5-4.5 USM Lens (Accessory)
I had mostly owned kit lenses before I bought this. That meant I found the improvement in image quality remarkable. It's wide enough to capture three walls of most normal sized rooms, and it gives a remarkable level of detail (I could read titles of books on bookcases even in the corner of the image on the widest setting). It also feels right in the hand. The controls are smooth with no play. I've not owned an L series lens so can't make comparisons, but I doubt that an enthusiastic amateur with a 1.6 sensor DSLR could hope for a wide angle lens better than this.
