The Camera Store TV provides an in depth comparison between the Nikon D800 and the Canon 5D Mark III. This is part one of a three part series. This first video compares the two cameras with help from studio photographer Nathan Elson. They give a slight edge to the D800 for detail and dynamic range, while the 5D Mark III shows significant improvement over the Mark II with its new auto focus system. Their conclusion is that in the studio, the two cameras aren’t very far apart.
They also take the cameras outside at night and here the two do begin to show some difference. The Nikon D800 again shows slightly more dynamic range and detail (sharpness), while the Canon 5D Mark III produces slightly less noise at high ISO.
The last part of the video includes side-by-side comparisons of the shots as well as the RAW images and examples of what post-production can do to bring out additional detail.
The video was shot using the Nikon D4.
