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. http://www.usa.canon.com/EOS-1D/faqs.html http://www.canon.co.jp/Imaging/EOS1D/pdt_shut.html 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. - Neil K. -- t e l a computer consulting + design * Vancouver, BC, Canada web: http://teladesign.com/ * **** ******* *********************************************************** * For list instructions, including unsubscribe, see: * http://www.a1.nl/phomepag/markerink/eos_list.htm ***********************************************************
