Agreed, Bill. the people who sold me my 1Ds (original version) said the very same thing... no sense pushing my luck. And, honestly, I've had less dust issues than I did before I learned this trick. This particular camera seems to attract dust like bees fly to honey. It has always been an issue, and turning it "off" before changing lenses DOES help the dust issue. The owner of the camera store I bought the 1Ds from jokingly said to me, "well, if it's really annoying, carry around a trash bag and duck inside it before you change your lenses." I would have laughed, but somehow it sounded almost plausible! Jane
