[QUOTE="hark, post: 594553, member: 13196"] Although I don't shoot at f/2.8 very often, there is an advantage to having fast glass. It allows more light into the camera which helps the AF. If you are in a dimly lit room, an f/2.8 lens may achieve focus while a lens that is f/4.5 or f/5.6 might be left hunting and not able to focus. And fast lenses tend to be made very well compared with similar lenses that aren't as fast. Not all fast glass gives nice bokeh when shot wide open. It all depends on the lens. [/QUOTE]
