  The 1D has a conventional shutter but according to Canon it's only 
used as physical protection for the CCD imaging chip and for long 
time exposures in bulb mode. Normally the 1D relies on an electronic 
shutter, which is how it gets its incredibly high top shutter speed 
of 1/16,000 sec and top flash sync of 1/500 sec.

  The D30 does not appear to use an electronic shutter. Its manual 
states that its shutter is a "vertical-travel focal-plane shutter 
with all speeds controlled electronically," which is the same 
description used on film cameras. The D30 also has a top shutter 
speed of 1/4000 sec and a flash sync of 1/200, like a semi-pro film 
camera.
