Nikon D800 Digital SLR
Nikon's newest format DSLR with groundbreaking 36.3 megapixels and the powerful EXPEED 3 image-processing engine offers imaging potential that rivals some of the best studio cameras, but with the agility and durability of a Nikon digital SLR body. Depict the slightest change in light or shadow, on a piece of jewelry or in the glow of human skin. Still images reach a completely new height with unprecedented depth and details, both indoors and out.

Nikon's exclusive 91K-pixel RGB sensor enables the Advanced Scene Recognition System to detect human faces even when shooting through the optical viewfinder, adding even more of an edge to your AF, AE and i-TTL flash performance. If your workflow demands broadcast quality video with high-fidelity audio recording, D-Movie will satisfy even the most demanding clients. Moreover, the D800 shoots 1080p Full HD in both FX- and DX-based formats, offering cinematographers total versatility.

The EXPEED 3 image processing engine with 14-bit A/D conversion and 16-bit image processing offers superb tonal gradation. EXPEED 3 manages massive amounts of data at faster speeds than EXPEED 2. Even with specialised processing features like Active D-Lighting and high ISO noise reduction, capture speed is not affected. EXPEED 3 is so powerful that it handles data-intensive tasks such as Full HD video recording at 30p with ease. Still images and videos have minimal noise and even richer colors and tones. In addition to these fundamental advantages, the D800 reduces the kind of color phase shift that some cameras have difficulty with in similar situations.
