A few weeks ago we were introduced to Nikon’s inadmissible new flagship, the D4. The $6000 DSLR camera has many ISO steps, a 16.2MP sensor, a new processing core, loads of professional features. If you are a Nikon photographer, who needs a camera that can do it all, the D4 is probably the best solution; but this camera is very expensive and many features you just might not need, like built in Ethernet connection. Amateurs prefer the D800 camera, it is cheaper.
The Nikon D800 is the replacement of the company’s $3000 D700 camera. As a consequence, the camera is similar to D4, with a reduced set of features and some significant adjustments, but not as much as the D700 was such the Nikon D3. The Nikon D800 is not a fully comparable camera and it will rest distant from the D4 in some crucial field.
