peevee1: What's with people demanding RAW on a camera with 16 million pixels on a tiny 1/2.3" sensor? Look at the pictures, they have noise (VISIBLE IN JPEG!) even at base ISO!
What do you expect from RAW, more encoded noise? Because JPEG at max quality already encodes 12 bit/pixel, and those tiny pixels don't have even 10 bits of information (as opposed to noise) in them!
Want to correct the picture - go ahead and correct the JPEG. Same thing. RAW is not going to turn these 16 mpix into 16 mpix from D4s!
Besides, except on Oly and Pentax at the very wide end, these pixels are way smaller than Airy disks, and even then Bayer-interpolated! Downscale 4:1 and stop fooling yourself.

I need RAW to tweak noise reduction to my taste. I prefer more details and more noise. Also, having RAW allows to use time-consuming noise reduction methods. In future, new noise reduction algorithms will surely appear, and this will allow me to improve my old photos. I almost always shoot RAW with my Canon PowerShot A1300 + CHDK (16MP 1/2.3" CCD).

Jan Toude: There is some chromatic aberration (color fringing) in the Nikon 1 AW1 underwater photographs. Fortunately, it can be removed in post-processing (I tried this today).

An example of color fringing removal (DSC_0072 from the DPReview Nikon 1 AW1 gallery):

In reply to:

groucher: Good review but please DPR stop referring to this camera as an 'underwater camera'. It is far more than that. Anyone with an interest in outdoor activities from caving to mountaineering and everything in between could be interested in this camera whilst 60 fps makes it the ideal camera for ball game photography and birding, particularly in the soggy UK. Wish I had one to photograph today's storm.

The AW1 desperately needs a viewfinder though. Using a rear display in harsh conditions is difficult.

@stupidisanart:
> The 60fps has a really bad IQ to manage it
Lumix GX7 shoots in reduced resolution JPEG at 40fps. On the contrary, my Nikon 1 J1 produces very good RAW photos at 60fps.

Weather sealed compact system camera with good sensor (little channel crosstalk, high DR, high resolution, fast readout) and open application programming interface.
