1. New Nikon FX-format CMOS image sensor
    Support for an incredibly wide range of sensitivities, from ISO 50 to ISO 204800

    The D4 is equipped with a new Nikon FX-format CMOS image sensor (imaging size of 36.0 x 23.9 mm) developed by Nikon. The superior performance of the FX-format CMOS image sensor with its effective pixel count of 16.2-million pixels offers excellent resolution and image quality under an incredible variety of lighting conditions. Despite the increase in pixel count, the D4 reads out data faster than the D3S. The range of standard sensitivities has been expanded to ISO 100 to ISO 12800. What's more, support for ISO 50 and additional expansion up to ISO 204800 is also possible, enabling effective shooting under a variety of lighting conditions without concern for any sacrifice in image quality.

  2. New EXPEED 3 image-processing engine with superior, high-speed processing capabilities

    The new EXPEED 3 image-processing engine built into the D4 offers better image quality and even faster processing speeds for vivid yet faithful color reproduction, a broader dynamic range, and rich expression of tones. It also effectively suppresses noise with advanced noise-reduction processing for images captured at high sensitivities under dim lighting, all while preserving definition and sharpness. Noise-reduction processing designed especially for movies maintains crisp, clear outlines in movies recorded in low-light situations. EXPEED 3 has high-speed processing capabilities for a variety of task, and it uses power effectively, contributing greatly to the camera's power-saving design.

  3. 91K-pixel RGB sensor for the more accurate Advanced Scene Recognition System

    The D4 is equipped with the Advanced Scene Recognition System, which supports face recognition* when images are framed using the optical viewfinder. The new 91K-pixel (approximately 91,000 pixels) RGB sensor recognizes human faces for more frequent focus acquisition on human faces when Auto-area AF AF-area mode is used. When a human face is detected in the frame, 3D Color Matrix Metering III bases exposure control on the brightness of that face so that the face is optimally exposed even with backlighting. In addition, the high resolution of the metering sensor with its roughly 91,000 pixels enables extremely precise analysis of the scene for more accurate control over autofocusing, auto exposure, i-TTL flash control, and auto white balance.

    • *There is no display in the viewfinder that shows when a face or faces have been recognized.
  4. Faster and more accurate AF with 51 focus points

    The 51 focus point AF system built into the D4 utilizes the new Advanced Multi-CAM 3500FX autofocus sensor module for faster, more accurate autofocusing that performs extremely well under dim lighting.
    The 15 focus points at the center of the frame are cross-type sensors that detect phase differences both horizontally and vertically. All 51 focus points are fully functional when lenses with a maximum aperture of up to f/5.6 are used, and the cross-type sensors make the most of this capability. Precise focus can be quickly acquired with autofocusing using all AF NIKKOR lenses, even under lighting as dim as
