im Vergleich zur LX5
"The ability to reproduce color, for example, is neck-and-neck between the two. At other times however, the LX5 lags behind. Noise performance is downright poor, and resolution isn’t quite what it should be. The LX5’s mixed bag cannot compete with the S100’s consistent excellence, so our recommendation here should be obvious."
zur XZ-1
"Times change, and the XZ-1’s rank has dropped a bit, but this camera remains one of the best ultracompacts out there. But the S100 is better.
The margin is very slim, a few points here, a few points there; but by most metrics the S100 wins. Noise is the biggest difference between the two, thanks to the S100’s clear shots at low and medium ISOs. Canon also surpasses many of the XZ-1’s best features, such as burst mode and shooting controls."
