D4 Primary Features

New Nikon FX-format CMOS image sensor and ISO 50 to ISO 204800

The D4 is equipped with a new Nikon FX-format CMOS image sensor (imaging size of 36.0 × 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.

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 colour 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.

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 recognises human faces for more frequent focus acquisition on human faces when Auto-area AF is used.

*There is no display in the viewfinder that shows when a face or faces have been recognised.

Faster and more accurate AF with 51 focus points

The AF system featuring 51 focus points utilises 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 −2 EV (ISO 100, 20°C/68°F), the level at which the scene through the viewfinder can just be made out by the human eye.

*Except lenses for F3AF

In addition, 11 focus points (five at center with an additional three to each side) are fully functional when lenses with a maximum aperture of f/8 are used. This enables very precise focus acquisition with sports photography and the like when super-telephoto NIKKOR lenses are used with a teleconverter (2.0×) at a combined aperture value of f/8.

Adoption of a new algorithm enables faster autofocus initiation for even more certain and sharper capture of defining moments especially necessary when shooting sports scenes. The new high-speed AF system also supports high-speed continuous shooting at approximately 10 fps* in FX format with AF and AE tracking.

*Measured according to CIPA guidelines. Value with shooting in AF-C autofocus mode, [S] or [M] exposure mode, shutter speed of 1/250 s or faster, all other settings at their default values.

Multi-area Mode Full HD D-movie with three image area options

A dedicated movie-record button has been positioned near the shutter-release button for smooth starting and stopping of movie recording with a feel similar to that of still-image shooting. Full-HD movie recording at a frame size of 1920 × 1080 and frame rate of 30 fps is supported, and the H.264/MPEG-4 AVC video compression method has been adopted. Movies up to 29 minutes 59 seconds can be recorded. Image sensor sensitivity begins at ISO 200 and can be expanded to the same ISO 204800 equivalent possible with still-image shooting.

Full-HD movies can be recorded with the D4 using one of three image areas: FX-based movie format*, DX-based movie format, or 1920 × 1080 crop; all available at 30 fps/ 25 fps or 24 fps. FX-based movie format makes full use of the large image sensor, enabling movies with an emphasis on pleasing blur characteristics. When a DX lens is attached, DX-based format is automatically selected. This format is useful for creating an extension to the focal length of an existing lens. For an even stronger telephoto effect, the 1920 × 1080 crop format brings an approximately 2.7x crop of the picture angle while delivering outstanding video quality and detail, obtaining 1080p Full HD.

The D4 is equipped with a connector for external microphones that enables stereo recording. The camera also offers a headphone connector that supports stereo headphones, convenient for checking sound recorded with movies. What’s more, a new sound level indicator also allows for microphone sensitivity adjustment, even during recording, with a visual indicator of sound levels.

Movies are recorded with an aspect ratio of 16: 9 regardless of the format selected. Aspect ratio is 3 : 2 with recording at a frame size/rate of 640 × 424; 30 fps and 640 × 424; 25 fps.

Smooth workflow from initial setup to image transfer

The entire photographic workflow is faster with the D4. Superior, high-speed response with a power-up time of approximately 0.12 s¹ and a release time lag of roughly 0.042 s¹. In addition, support for high-speed, next-generation XQD memory cards enables a continuous shooting frame rate of 10 fps for up to approximately 100 shots even with shooting in RAW format². The camera is also equipped with dual memory card slots, one for XQD memory cards and one for CompactFlash memory cards, for smooth handling of images. What’s more, professional photographers can work much faster with high-speed transfer of images to a computer when an XQD memory card reader supporting SuperSpeed USB (USB 3.0)³ is used.

The new compact Wireless Transmitter WT-5 with simple connection to the camera (available separately)

The D4 is equipped with an Ethernet port and functions for wired LAN connections. In addition, it also supports the new WT-5 (available separately), a compact wireless transmitter that is easily connected to the camera for high-speed transfer of images over a wireless network.* The D4 is also equipped with a number of new functions that support a more efficient workflow for professional photographers, including one that allows users to add IPTC (International Press Telecommunications Council) information to images.

The new WT-5 is powered by the camera, making a more compact size possible. In addition to IEEE 802.11a/b/g standards, the H062 also supports the new IEEE 802.11n (1 × 1) standard, enabling data transfer at twice the speed possible with the WT-4. The camera’s HTTP server mode can be used to display a list of images stored on the memory card, and also enables basic camera control, live view, movie recording, etc. using the Web browser on a computer or smartphone. Synchronised release (WT-5) mode enables synchronised shutter release of up to 10 cameras (D4 cameras, each with its own WT-5) with the D4 used as the controlling “master".

*The Wireless Transmitter WT-4 can also be used.

Capture NX 2 Ver. 2.3 for significantly faster processing

A trial version and free upgrade for Capture NX 2, Nikon’s image editing software, were released on December 20 to coincide with release of the D4. This latest version is Capture NX 2 Ver. 2.3. 

In addition to offering image editing functions that provide intuitive operation, a faster image-processing algorithm has been adopted for much faster processing. What’s more, operation is smoother and more natural with the addition of native compatibility with 64-bit operating systems.
