Just started using my 20D today. right now i'm only using the large jpeg/fine setting in continuous mode and also ai servo. my iso was set to 400 and SS 1/800 sec. well i thought i was supposed to be able to continuous burst to 20 frames. the camera shows me only 9 frames and counts down and then counts back to 9 while storing. why only 9 frames?? why not 20 frames?? also, i don't think the 20D shoots at 5fps unless there is an option or function i missed. i guess i'll have to take a closer look at the manual for that one.

all in all with the few pics i took i am quite pleased with the camera and the 100-400mm performance. it sure is nice to be looking through a nice bright and clear optical viewfinder again. camera and lense combo is heavy but manageble.

In A1 Servo mode the camera has to gain focus prior to releasing the shutter which can give you less than 5 fps. In one shot mode focusing is not executed between shots for continuous shooting.

Also, from the manual regarding the 20 frame burst:

"Varies depending on the subject, ISO speed, processing parameters, CF card, etc."

By the way, what card are you using? Using my Sandisk Ultra II I was able to fire off 40+ and 60+ continuous shots in JPEG Large/Fine (depended on lighting)at Iso 100.

Bob, thanx!!! I put the camera in one-shot mode and the burst was a lot faster. In ai servo it really slowas down, as you mentioned, due to focus. I read the manual and the 9 frames remaining indication just means there could be more than 9 remaining. i did a burst of about 20 frames in both ai servo and oneshot. i use a snadisk extreme III card (1G). it was supposedly the fastest for the 20D according to Rob Golbraith's site.

The viewfinder can only display 1 digit for the frames remaining, so it shows 9. I was confused at first as well. But I've gotten a 29 frame burst when I was first trying the performance of the camera.
