Speed & Performance
The Olympus shoots at 3 fps in RAW, and has a buffer of 10 frames. They add that on the “Sequential Shooting” in large, normal JPEG mode you get about 12 total shots with, for example, the Toshiba Super High Speed type "Class 6" 4GB cards. The Canon also reaches about 3 fps with a buffer of 10 frames in RAW, 27 in large, fine JPEG and 8 frames at RAW+JPEG. Nikon claims a 4 fps, and doesn’t give us any more info online.

The jury’s out on the Autofocus and write speeds, especially as far as the high and normal speed cards go. Once we have that work done, it will be added to the review, but for now our conclusion is that the three are pretty much on equal footing in the speed arena, which is not surprising. Again, they are what they are - under $1,000 cameras that are best for relatively spontaneous shooting. Would we depend on any of them for a once-in-a-career job shooting high-speed motorsports? …probably not.
