Man I love this lens. I had only shot with zooms until I bit the bullite and bought this baby. I really like it for shooting 10Ks and other running events. The pictures are superb, sharp, with beautiful color and great bokeh. This lens really performs and I also use it with a 1.4 tele which gives me a super fast 190/2.8. If you shoot action such as running events this is the lens for you. Currently I am using it on a 20D and it performs flawlessly. It you like primes and want the best of the best get this lens. I promise you will not regret it.
