So I've been using this camera for about 4, 5 months now. Here's my personal take on it.
General
1. The camera is more portable and lighter than my DSLR (duh!), so I tend to take it out shooting more
2. The camera is less obtrusive (smaller and quieter) so people don't mind it as much as a DSLR
3. The magnesium overcoat is easily scratched
4. The viewfinder glass(?) coat is easily scratched
5. Friends and strangers both like the way it looks and handles!
Usage
1. Autofocus success is probably front-focused by a smidge.
2. Autofocus failure (it says it's in focus but actually not) happens maybe 10% of the time. This happens more in very bright or back lit scenes.
3. I use the EVF all the time now because it shows me what the sensor sees
4. Yes, the autofocus is slow, but this isn't a DSLR
Color
1. Reds don't look right (reds look orange), and no setting will fix it
2. Saturation is a bit high, but can be dialed down
3. I've dialed down the flash for a better subject-to-background transition
Noise
1. JPG engine smoothens the image a lot
2. Noise level is well-managed
3. The RAW file of course shows you the raw noise too (looks bad at higher ISO), but can be adjusted by software
4. Usable max ISO appears to be either ISO 1600 or ISO 3200 depending on your taste; I can't use ISO 6400 because of artifacts
My settings
Provia, Auto ISO (200 - 3200, lowest shutter speed 1/60), Color tone -1, Shadow tone -1
