The sensor's full pixel count of 18MP is never used (output size tops out at 16MP in 4:3 mode), but viewed critically, image quality is excellent in all of the available aspect ratio modes.

9.0
10.0
It has a 24.6-megapixel CMOS sensor, built-in sensor-shift image stabilisation and sensor cleaning, 5fps shooting in Raw+JPEG mode, a tough weatherproof body and what is widely acclaimed as the best viewfinder on the market.

Many of the new capabilities definitely target pros: a pair of low-resolution raw formats (10 and 5.2 megapixels), more interchangeable focusing-screen options, in-camera peripheral-illumination correction to compensate for brightness nonuniformity across the image, and a silent Live View mode.
