The Canon EOS 5D Mark II is an advanced development of their enormously-popular 5D camera, a segment-defining unit which truly stood the test of time in an ultra-competitive and constantly-evolving industry.  The sum of its improvements are indeed impressive; it is a tool that can satisfy the demands of advanced photo enthusiasts built to the specifications needed for professionals.

Continuing with the elegant principle of a 'full frame' sensor in a rather compact body, the 5D Mark II adds many valuable features which have arrived to the DSLR setting since the original 5D's August 2005 debut.  Chief amongst these are a much improved LCD screen with a viewing mode on the LCD screen itself, and a movie mode for simulating a camcorder's ability. 

It also adds a few more 'classic' features that weren't in the 5D, such as a vibrating self-cleaning system for the imaging sensor and a weather-sealed housing.

Working photographers will appreciate the improvements in shutter durability, weather sealing, and autofocus micro adjustment which aim to make the 5D Mk II a viable professional's alternative.  Camera enthusiasts who seek the best possible image quality will love the live viewing mode that can also simulate a camcorder; a video shot with an EF 85mm f/1.8 wouldn't be your typical ubiquitous vacation clip by any means, and being able to use an SLR overhead while composing from the LCD screen opens up new possibilities for any shooter.

Perhaps best of all, they managed to pack all these capacities into a camera at a more economical price than its predecessor.

Features

• CMOS Sensor has >8Mp more resolution vs 5D (identical resolving power as EOS-1Ds Mark III) and expanded high-ISO range (ISO 50-25600 vs 50-3200)
• DiG!C 4 processor produces ~82 Mb/sec throughput, excellent high-ISO characteristics, & intelligent lens illumination pattern compensation
• Movie recording live viewing mode simulates camcorder with internal microphone, external microphone port, & HDMI video output (16:9 aspect ratio {1920 x 1080} up to 12 minutes)
• Contrast-detecting, 100% coverage autofocus live viewing mode keeps mirror up through successive exposures, reducing shutter lag & quieting exposures (manual focus also possible)
• Sealed magnesium housing (battery chamber, memory card door, LCD screen, and button/dial gaskets) with 150,000-cycle-specification shutter makes for a reliable professional's tool
