Features include a new 16.2-megapixel FX-format CMOS sensor
Like the D3 and D3s before it, the Nikon D4 retains Nikon's status as the sovereign of low-light capture ability, with a native ISO range from 100 to 12,800 ISO, expandable from 50 (Lo-1) to an incredible yet usable 204,800 (Hi-4). From a candlelit first dance to nocturnal wildlife, the large 7.3µ pixel size absorbs the maximum amount of light to excel in any situation. Additionally, the sensor's construction features a gapless micro-lens structure and anti-reflective coating which further contributes to images that retain natural depth and tones with smooth color gradation. For ultimate versatility, photographers can also take advantage of the camera's extreme high ISO ability while recording video.
Another factor contributing to the camera's rapid performance and stellar image quality is Nikon's new EXPEED 3 image processing engine that helps professionals create images with amazing resolution, color and dynamic range in both still images and video. From image processing to transfer, the new engine is capable of processing massive amounts of data, exacting optimal color, perfect tonality and minimized noise throughout the frame.
There are also a variety of shooting options available to help capture the highest quality images and video. In addition to standard NEF (RAW) files, the D4 is also capable of shooting smaller compressed RAW files to ease storage and speed up workflow. Users are also able to capture even more dynamic range with the in-camera High Dynamic Range (HDR) function that merges consecutive exposures. For deep contrast and further tonality, Active D-Lighting can also be activated during shooting for balanced exposures even in backlit scenes. Additionally, the camera features a dedicated button for quick access to Nikon's Picture Controls, allowing users to quickly select one of six presets.
Professional Multimedia Features
The Nikon D4 D-SLR is engineered with innovative new features for the multimedia professional that needs the small form factor, low-light ability and NIKKOR lens versatility that only an HD-SLR can offer. The new features add functionality for those professionals looking for the best possible experience to capture a moment in Full HD 1080p video at various frame rates, providing footage that is more than suitable for broadcast.
• Full HD video recording - Users have the choice of various resolutions and frame rates, including 1080p 30/24fps and 60 fps at 720p. By utilizing the B-Frame data compression method, users can record H.264 / MPEG-4 AVC format video with unmatched integrity for up to 20 minutes per clip. This format also allows for more accurate video data to be transferred requiring less memory capacity. The sensor reads image data at astoundingly fast rates, which results in less instances of rolling shutter distortion.
• Full manual control of exposure - Shutter speed, aperture and ISO can be changed while recording to adapt to lighting and alter depth of field for professional cinematic results that help realize a creative vision.
• Uncompressed output: simultaneous Live View - By using the camera's HDMI port instead of the CF or XQD card, users can stream an uncompressed full HD signal directly out of the camera. This footage can be ported into an LCD display or appropriate external recording device or routed through a monitor and then to the recording device, eliminating the need for multiple connections.
