Title: Favorite lens
Review: This is my favorite lens - fast, sharp, with great color and reasonable reach on my 5D. (When the light's bad I'll even use it indoors, just for the speed to avoid the glare of the flash.) Outdoors, the "big white lens" effect doesn't hurt, either: you can walk just about anywhere with this lens on a big body if you look like you know what you're doing, they just assume you're a pro.
