This first look review of the new 5D is provided by 'The Art of Photography'. The new release includes a variety of new features including dual pixel auto focus which allows for moving auto focus while shooting in video mode. Another very cool feature is the addition of a 4K shooting mode. Slow motion is also possible in camera, but at a loss of quality. 60fps is possible in 1080p, and 120fps is possible in 720p only.
Although a lot of the feature improvements seem to be improvements for video, there are a few updates in there which improve the photography ability of the camera as well. The main thing is the 30.4MB sensor, giving a huge amount of latitude and depth in every image.
