I am suddenly having problems with my S100. It will not take the picture when I press the shutter release. In case I had accidentally changed something, I did a Reset to Defaults. Then it worked, briefly, before returning to not working. It also would not let me change My Colors. Everything else seems to be working fine. Any ideas?
Regarding the comment made by Gary S., point well taken that most s100 cameras may be trouble free and the camera takes great pictures. But a problem is a problem, even if it affects only a fraction of the users. Our camera is a lemon. First it had the lens retract issue that Canon acknowledged and fixed for free. Now this second problem that required repair by Canon. In the age of Six Sigma, Canon should be stepping-up. Their response is unimpressive, suggesting that they either do not know how to fix the problem or just do not care.
I just stumbled across it going through my menu settings. It was on (perhaps by default?) and I changed it to OFF. It does seem to have helped in my case. I just returned from a few hours at the Acropolis in Athens and for the most part my S100 was snapping away. I was shooting mostly in P mode -- that seemed to work best. In Av mode at 2.0-2.8 it was very laggy again. I only shot jpeg -- didn't think to try shooting from RAW frames. We'll see.
