The Canon S1is got dropped on the floor. Fell out of my coat pocket as I got up. Fell two feet onto a linoleum floor. Checking it immediately, I turned it on, but the zoom lens did not extend. After a few moments, the camera turned itself off.
At home, I tried a few remedies, like putting in different batteries in case the increased power might help; trying to force the zoom lens out; banging the side of the camera. But nothing worked. This damage would not be covered by the extended warranty (though my credit card), so I'll have to pay for the repair.
The first time I used Canon's out-of-warranty repair service, it cost CDN$150 to fix a non-operating zoom lens on my older G1. The second time, they quoted $250 but the camera could not be repaired (damaged by sea water), although they did offer to sell me a newer model at a discount. It'll be interesting to see what the fee is this time; used S1 models are $350 on ebay.
I contacted Canon Canada, who gave me the addresses of three repair places in Ontario. (The Calgary facility has been closed?) I mailed it off, and will report on what happens next.
