Here are a few shots I took the other night using this lens on a Rebel XT. I have to admit, having an f/2.8 lens is absolutely AWESOME for night shooting. I must admit, I'm not super impressed with this lens for other types of shooting though, seems awfully soft unless you stop way down, and focuses very slow. Maybe I've got a bad copy, I'm renting it so no big deal really.
All of these shots were single exposures, most were taken at f/2.8, if not all of them. Usually between 20-30 second exposures at ISO 200.
