Re: Do Fast Lenses Matter Anymore?

Good point. Back in the film days, there was no question that faster was not only better, it was absolutely essential (I was shooting for newspapers). But these days--with ever better sensors--not so much IMO.

A faster lens would allow for a shallower depth of field to eliminate background clutter and, I suspect, the auto focus will lock on a bit faster, especially in crummy light. But the price difference between a 300 f/2.8 and a 300 f/4.0 might not be worth it with a good camera body. But another issue would be if you plan to slap a 2X extender on the slow lens--might cause some real headaches.
