With the 5D Mark III's large images files it is advisable to use a fast CF memory card, especially if you are planning to shoot bursts in Raw+JPEG mode.

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.
