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?
Same thing happened to my wife's S100 last summer (2015). I bought the camera as a refurb from Adorama, and got a New Leaf extended warranty. Sent in for repair and came back not having been fixed.Now I see this issue all over the place: camera will achieve focus lock, but will not fire. This is a premium pocket camera from a major company, and it sounds like if this happens to you, you're simply out of luck. A $170+ repair cost charged by Canon for what appears to be a manufacturing or design flaw? Seriously Canon, you guys need to recall these cameras and just fix them.
I find it very interesting that Canon are not replying now they can see that so many people are having the same problem.
I have the problem and my local Canon dealer cannot fix it, which I find very poor, and I don't see why I should have to try and repair the thing myself. I have always used Canon for years, but the last 3 cameras I have had issues with, and I am losing confidence in them.
What I have found very strange with my shutter release problem is that for long periods of time, i.e, months, the shutter release will not work then all of a sudden it will start working again. Just recently it has started to work again. This sequence began in 2014 after 2 years of ownership.
