gmke: Earthquake. Bye, bye, Canon GX1-MK-II. Faster glass, better sensor, All of a sudden, the fast glass, 2/3 sensor cameras are irrelevant too, except that they cost quite a bit less. Sony, premiere sensor maker that made Nikon big, has established a new category here, ThreeThirds, lets say, between FourThirds and TwoThirds. The question, down below a few, asks what factor (inversion of crop) would result in the use of a 12 megapixel portion of this sensor. Crop is 1.3, reciprocal is 0.77. Here is how it is obtained. 19,961,856 divided by 12,000,000 is about 1.663488. Take the square root. 1.2897 rounds to 1.3. 5472 x 3648 becomes 4242 x 2828, or 11,996,376.

That is assuming those 20 MP are all pure clean resolution which seems bit unlikely. But assuming that's true to get from 70 to 120mm will take a factor of almost 3. So that image is now a 7 MP (compared to typical 12 MP sensor). I wish they would have rather chosen for slightly slower higher quality 24-120mm. After all 1" is typically good at high ISO and you'll get more lens artifacts at f1.8 and 24mm (instead of slower lens at 24mm).

AnandTech low-light comparison to iPhone is pretty amazing:

On IMG_0363 photo in dpreview review samples's photo gallery (10 comments in total)

Nathebeach: To you naysayers, take a look at IMG_0363 (inside the airport terminal).
ISO 1600 and at full zoom, and not a lot to complain about. Nice.
My Olympus Pen Mini cannot do that unless I go down to 400 or better and then hand held is out of the question.

I wonder if that photo is fresh from the camera or if it was processed. Is there a way to find out?

I doubt dpreview post processes unless you mean in camera settings. jpg file looks normal with all EXIF data.

The file is small meaning high JPG compression. Hopefully it has super fine but you'd think dpreview would have chosen lowest compression if it would be available:-(.

You should be able to do this with Pen Mini since this is F5.6 (for some reason) which causes the slow shutter time.

This looks ok but I think SLR looks probably better at this ISO. But waiting for studio samples to do a direct comparison.

Peter Dhaeze: look at for ISO 1600 and 3200 JPEG straight from camera. DPP not available yet. Also comparison with EOS 60D.

There's just more noise reduction with the G1X and you can see actually more detail is resolved in center for the 60D (due to less NR).

That said the 60D kit lens is obviously not best with lots of CA and softness at the corners. It's 1 stop slower as well.
