Optimally, perhaps, but as fast as some cameras are - they can rip off
three shots fast enough to not matter. The new Sony SLR based on Minolta
technology can rip off shots at 5 FPS at it's full 12+Megapixel
resolution -- that three shots (bracketed) in .6 seconds... And with the
camera's "anti-shake" systems - the field won't move (the subject might
- but a tripod won't help in that case either).

best regards...
