Hi I got a very newbie question to ask. Is the burst mode of a cam dependent on the type of memory card used? Eg. my camera is supposed to be 3fps, but I realised that when I am shooting continuous mode, the memory card only gobbles up to 3-4 pics then slow down liao.. The jpeg was set to the highest quality. The camera is supposed to be able to do much better than that. Whats wrong? I am using those normal CF/SD cards. Not high speed one, is the most normal type. And if I want to shoot sports, besides a fast lens I will need a fast memory card too?
