The problem with leaf shutters on standard cameras has to do with size and mass, and, of course, acceleration. Such shutters are much larger and heavier than the shutters on the small digicams. At some point the larger shutters are unable to maintain accurate shutter speeds. This has often been determined to be @ 1/500 second, although many users of cameras with leaf shutters suggest that even 1/500 second is often "slow" and not close enough to be accurate. I have heard of people using the 1/500 speed as 1/350 when they are looking for very accurate exposures.
