After much waiting, Canon finally unveiled the EOS 5D Mark III last week, marking the 25th anniversary of the EOS system. The all-new EOS 5D Mark III has got upgraded from its predecessor 5D Mark II and sports several new features.
However, with the release of the Mark III, Canon expects to give tough competitions to its rivals. The on-going rivalry between Canon and Nikon is nothing new. Both the companies have recently upgraded their high-end version of cameras with Nikon replacing the D700 with the D800, while Canon replacing its EOS 5D Mark II with the EOS 5D Mark III.
Both the cameras have their own pros and cons, but none of them stand out of the box when it comes to originality or something new. All I can say is that both the cameras have been enhanced a lot in terms of features and specs.

Nevertheless, we’d still want to compare what each of the cameras have in different, particularly when it comes to features and technical specifications. Here’s a comparison of the Canon EOS 5D Mark III vs. Nikon D800 -

Nikon definitely surprised every photography and camera enthusiasts on earth when it released its D800. The Nikon D800 sports a massive 36 million pixel sensor with a huge jump from the 12.1 MP sensor in the Nikon D3, which was released in 2007.
Certainly, everyone expected that Canon would release its next camera with a similar sensor in order to compete head-to-head against the D800. However, Canon decided to play a completely different game by releasing the EOS 5D Mark III with a 21 million pixel low-resolution sensor, focusing on better image equality and noise reduction characteristics along with improved features on AF features/performance and weather sealing.
The reason being is that Canon has been receiving a lot of criticism from the Canon community for over several years on these areas, and that isf why Canon decided to listen to what its community has been saying. It is definitely a smart move from Canon specifically with the autofocus features and performance.
Most of the users from the community are stating that the EOS 5D Mark II should have sported the features what the EOS 5D Mark III currently has. I agree to some extent, but when it comes to image quality, I disagree with the statement.
The Canon EOS 5D Mark III has significantly improved in its autofocus features by introducing 61 points – a big upgrade from the Mark II, which only has 9 autofocus points along with 6 assist autofocus points. However, the Nikon D800 offers 51 AF points, with 15 cross-type sensors.
Nikon has improved the D800 video features a lot, especially with the options to shoot at different frame sizes for different focal length and depth of field effects, as well as 50p and 60p slow-motion capabilities. The video offerings in the Canon EOS 5D Mark III and the D800 are pretty much the same, since both have the capability to shoot full HD videos.
