Features a 36.3-megapixel FX-format CMOS sensor
For shooting with minimal noise in a variety of lighting conditions, the D800 features a wide native ISO range of 100-6400, expandable to 50 (Lo-1)-25,600 (Hi-2). Nikon engineers have created innovative ways to manipulate light transmission to the sensor's photodiodes, giving users the ability to shoot with confidence in challenging lighting conditions. Internal sensor design, an enhanced optical low pass filter (OLPF) and 14 bit A/D conversion with a high signal to noise ratio all contribute to a sensor capable of excellent low light ability despite the extreme resolution. Every aspect of this new FX-format sensor is engineered to deliver amazing low noise images through the ISO range and help create astounding tonal gradation and true colors, whether shooting JPEG or RAW. Images are further routed through a 16-bit image processing pipeline, for maximum performance. To further enhance versatility, users are also able to shoot in additional modes and aspect ratios such as 5:4 to easily frame for printed portraits or a 1.2X crop for a slight telephoto edge. For even more versatility, photographers can also take advantage of Nikon DX-format lenses for more lens options and enhanced focal range (1.5X), while still retaining sharpness and details at a high 15.4-megapixel (4800x3200) resolution.
Contributing to the camera's rapid performance and amazing image quality is Nikon's new EXPEED 3 image processing engine that helps professionals create images and HD video with amazing resolution, color and dynamic range. From image processing to transfer, the new engine is capable of processing massive amounts of data, exacting optimal color, rich tonality and minimized noise throughout the frame. Despite the immense data, the new EXPEED 3 also contributes to energy efficiency, affording the ability to shoot longer.
The D800 also features the Advanced Scene Recognition System with the 91,000-pixel 3D Color Matrix Meter III to provide unrivaled metering in even the most challenging of lighting conditions. At the system's core is a newly designed RGB sensor that meticulously analyzes each scene, recognizes factors such as color and brightness with unprecedented precision and then compares all the data using Nikon's exclusive 30,000 image database. Additionally, this new sensor now has the ability to detect human faces with startling accuracy, even when shooting through the optical viewfinder. This unique feature is coupled with detailed scene analysis for more accurate autofocus (AF), Auto exposure (AE), i-TTL flash control and even enhanced subject tracking. The Color Matrix Meter also emphasizes priority on exposure of the detected faces, allowing for correct exposure even when the subject is backlit. Even in the most difficult exposures the D800 excels, such as maintaining brightness on a bride's face while retaining the dynamic range to accentuate the intricate details of a wedding dress beside a black tuxedo.
Advanced new automatic systems make it even easier to capture amazing images. The camera features a new enhanced auto white balance system that more accurately recognizes both natural and artificial light sources, and also gives the user the option to retain the warmth of ambient lighting. Users can expand dynamic range with in-camera High Dynamic Range (HDR) image capture, and enjoy the benefits of Nikon's Active D-lighting for balanced exposure. Another new feature is direct access to Nikon's Picture Control presets via a dedicated button on the back of the body to tweak photo and video parameters on the fly, such as sharpness, hue and saturation.
