Originally posted by pingflood While I haven't counted fps I have not noticed a slowdown when shooting birds in flight with my 50D. It chugs along at what sounds like full speed, though I suppose I could do some testing and see. From what I recall reading though only certain lenses will really drag a 40D/50D down, and they are the ones where the AF and diaphragm operations are sequential (mostly cheaper glass).
I own a 1DS MKIII and yes, a 50mm f/1.8 will cause FPS to drag, but if you use something like at 85mm f/1.8 which has a ultra fast ring USM motor - things speed up. However, when you use Constant AF with a subject moving in irregular patterns things get more complicated. and the AF will drag thus slowing down the FPS.

They didn't, so they made do with what they had. Having a well performing DSLR body doesn't make you into a good photographer, but a good photographer can likely get better results using one.
yes they probably could, but they all did superbly with what they had didn't they?...Personally I consider differences of 1-2 FPS to be inconsequential. people who make issues of trivial things like this I brand as a special species of troll: the white paper troll.... they glorify the features that look better on white paper no matter how small a difference they actually make in actual usage. They are not to be confused with measurebators who will try to measure some trivial difference between Apple and Orange and declare the apple the winner by virtue of their own biases...just look at the holy war that is still burning between the Konica Hexar RF and the Leica Rangefinder camp. fundamentally speaking the only difference between a Hexar RF and a leica M7 is 0.03mm at the film gate.
