5x zoom lens with an aperture range of f/1.8-2.8? Looks good.
But this release is kind of late to the already crowded market, isn't it? We now have Panasonic LX7 with a f/1.4-2.3 4x zoom, Olympus XZ-1 with a f/1.8-2.5 4x zoom and Fujifilm X10 with a f/2-2.8 4x zoom. Then, there's also the Sony RX100 with its slow lens but big sensor.
Ultimately, in real use, I suspect all the above cameras will have rather similar image quality (the big sensor advantage of the RX100 is offset by its slow lens). And Canon will be the overall loser 'cos they still suffer from slow contrast AF algorithm. Sigh...
