Conclusion: Have owned this camera for less than 2 weeks. I shot more than 300 photos with it and LOVED the IQ and was not bothered by the slow auto focus. HOWEVER, the camera freezes up -- I get a white screen, the shutter won't fire, the menu button doesn't work. This has happened 3 times in less than two weeks; the first 2 times I removed the battery and waited a bit, reinserted the battery and all was OK. 4 hours ago this happened again and the 'normal' fix is no longer working.
Pros: quiet, excellent image quality, Superior build quality, easy to use
Conclusion: I have many Canon cameras from point and shoots to a 1D-X (which I love). Getting the EOS-M for my wife was a no-brainer when it came out. The quality of construction and features are every bit as good as I would expect from Canon, but the fatal flaw is focusing - of fast moving objects, or stationary objects in low light. I took the EOS-M to a party and the focusing in low light was so poor I had to give up in the end.
Pros: excellent image quality, Superior build quality, Bright LCD
Cons: Difficult to use, poor focusing in low light, poor focusing of fast moving objects
Summary: Wirklich schade: Schönes Design. Liegt gut in der Hand und für Schnappschüsse WÄRE sie gut zu gebrauchen. Die Handhabung wäre gerade dafür gut abgestimmt. Auch toll, dass man die Objektive der Spiegelreflexserie mitbenutzen könnte. Der tolle große Sensor (APS-C). Alles könnte gut sein, ist es aber nicht. Aber warum alles im Konjunktiv? Ganz einfach: Der Autofocus ist eine Katastrophe und macht die Kamera im Prinzip unbrauchbar.
