http://www.dpreview.com/reviews/canon-eos-5d-mark-iii/25Although the specification on the box says 1080p, with regards resolution the 5D Mark III is a huge let down and the $600 Panasonic GH2 offers a far more detailed 'true 1080p' image (whilst maintaining a relatively large sensor for video and interchangeable lens mount). The 1080p mode is not really full HD atall in terms of the real amount of detail in the image - more like 720p.
The 5D Mark III is vulnerable since it is not a huge step from the 5D Mark II in terms of the overall image in video mode. Other cameras such as the $5000 Sony FS100, $800 Panasonic GH2 and $3000 Blackmagic Design Cinema Camera offer significantly more in the ways of features and image quality for low budget video production.
