Canon EOS 5D mkII
Compact, lightweight and with environmental protection, the successor to the EOS 5D boasts a newly designed Canon CMOS sensor, with ISO sensitivity up to 25,600 for shooting in low light conditions. The new DiG!C 4 processor combines with the improved CMOS sensor to deliver medium format territory image quality at 3.9 frames per second, for up to 310 frames.
Triggered from Live View Mode, HD video capture allows users to shoot uninterrupted at full 1080 resolution at 30fps – for amazing quality footage with outstanding levels of detail and realism.
The integration of HD movie capability into a high-end 21.1 Megapixel camera opens a multitude of new possibilities for photojournalists and news photographers. With its full frame CMOS sensor and outstanding ISO performance, the EOS 5D Mark II will appeal to any photographer in search of the finest camera equipment available – from studio and wedding to nature and travel photographers.

From what I’ve seen, this second version appears to be just what users of the ageing 5D need to keep on top of their game. It’s fast, powerful, advanced and keen.
