the way it is. I think, although I'm not sure, that it has a sufficient internal buffer. At least once, I've noticed that it's still writing to the card after I'm done shooting. I have also upgraded to a fast card just to be sure.
I just like taking pictures mostly of my son. I have a Canon G3 and it takes great pictures. However, I have new camera fever and want to get one that is faster (to take pics of little league sporting events, stuff like that)- and wonder if the Canon 20D that says it takes 5fps is worth the extra about $400 than the XT which says it takes 3fps- I played with both at best buy and could tell a little difference (the 20D being faster), but there also was no cf card- they are both extremely fast without the card. I know both cameras are well beyond any capabilites I would need, but I am interested in speed and want to stick with Canon as my G3 has been great except for the speed.
