Tested this lens on a 7D and works flawlessly. I got this lens initially to use with my Birger Mount but it doesn't.
Info I got from, fredmiranda.com
Description:
Highly portable lens with high optical performance and light weight of 12 oz. (340 g). A very practical ultra-wide-angle zoom. The large front lens group minimizes peripheral darkening, and the flare-blocking diaphragm minimizes flare. Also, with lens group 2 being the zoom group, distortion is corrected.
It's much more solid than lenses of late. Feels much more "metal" - hard, smooth, and compact. The zoom ring turns smoothly and easily. Here is a quote to give you more of an idea: "This canon 20-35 2.8L lens is really the "lux" of canon lens. Some people complain about the speed of a non-usm lens and in my humble opinion ( Brussels National Geographic partner for 18 years ) I must say there is no difference at all. One is constantly on my canon 40D and another one on my canon 5D. The 2.8 gives me the most perfect bokeh. Highly recommended... "
