Nikon D4s DSLR Camera

The 16.2-Megapixel Full-Frame Nikon D4S Blends Performance, Fast Operation, Incredible Optics and Innovative New Features to Capture High Quality Photo and HD Multimedia Content.

The new EXPEED 4 image-processing engine, together with a redesigned Nikon FX-format CMOS image sensor with an effective pixel count of 16.2 million pixels, enable photographers to capture images with stunning sharpness, enhanced depth, and natural skin tones. A range of standard sensitivities from ISO 100 to ISO 25,600 produces images with sharper edges and smoother, richer colours. The D4S also supports extended sensitivities as low as the equivalent of ISO 50 and as high as the equivalent of ISO 409,600.

The Ethernet port speed has been increased to 1000BASE-T support for wired LAN communication, making it possible to have extremely fast image transfer. A RAW S Small (12-bit uncompressed RAW) setting has also been added for faster post-capture editing on a computer.

Very precise adjustment of AF algorithms based on the Advanced Multi-CAM 3500FX autofocus sensor module enables accurate acquisition of even erratically moving subjects and even those exhibiting little contrast. The improved autofocus keeps the acquired subject in focus, even when it is coming closer, or moving away, at high speed. What's more, the D4S offers better balanced AF control with more precise focusing on the intended subject, and more accurate tracking of that subject, even when photographing team sports, such as soccer and rugby, when action may temporarily obstruct the intended subject.

In addition to the four time-tested modes built into the D4 - Single-point AF, Dynamic-area AF (9-, 21-, 51-point), 3D-tracking, Auto-area AF - the D4S is equipped with a new Group-area AF AF-area mode for more powerful and versatile autofocusing. When Group-area AF is selected, the camera uses one focus point selected by the user and one each above, below, to the right, and to the left of the selected focus point, for a total of five focus points, for focusing. By capturing the subject within the five-point group, even if it is small and moving quickly and erratically as is often the case when photographing athletes and animals, the intended scene can be captured with greater certainty without focus shifting to the background.

Auto white balance achieves healthier, more vivid skin tones under a variety of lighting conditions. Adoption of a new image analysis system enables more accurate extraction and identification of white portions within the frame. In addition, as white balance can be fine-tuned in smaller steps than ever before, more precise settings can be specified. The D4S is also equipped with a spot white balance option that allows users to manually measure white balance data beforehand from even a very small white or grey portion of the frame. When the D4S is unable to accurately or satisfactorily measure preset white balance data, simply changing the area from which data is measured as many times as needed eliminates the need for repeating the process from the beginning. This helps to increase shooting efficiency for professional photographers who must work quickly when on-site.

A new RAW S Small option4 that records images using 1/4 the number of pixels used for full-sized RAW images has been added. This makes editing images on a computer after they have been taken faster and more convenient (file size is approximately 1/2 that of 12-bit uncompressed RAW L Large images).

The D4S is equipped with a 3.2-inch, approximately 921k-dot wide viewing angle TFT LCD monitor with which the protective glass and LCD panel have been integrated to suppress internal reflections. Display characteristics have been carefully adjusted for more faithful colour reproduction. In addition, the camera is equipped with a function that allows users to customize colours to suit their individual preferences.

Movies recorded at a frame rate of 60p exhibit smooth subject movement and changes in exposure, even when the brightness of the scene changes greatly. Noise is effectively suppressed throughout the full range of standard sensitivities (ISO 200 - 25600) for rich expression of tones and stunning sharpness that preserves details. The D4S offers selection from three image area5 options that respond to imaging intent FX-based movie format, DX-based movie format, and 1920 x 1080 crop. With recording at a setting of 1920 x 1080 crop, 1920 x 1080p Full-HD movies are generated without resizing for stunningly sharp movies that are rich in detail. Changes in exposure are also better controlled for smoother transition between frames with recording of scenes in which brightness changes greatly, even with time-lapse movies.

In addition, uncompressed movies can be recorded directly to an external HDMI device connected to the camera's HDMI connector in movie live view mode. A dedicated HDMI cable clip is supplied with the D4S. When used with the optional HC-E1 HDMI cable, this clip prevents accidental disconnection of the HDMI cable from the camera. In addition, movie recording with the D4S is even more convenient as movies can be recorded to an external HDMI device and a memory card inserted in the camera at the same time.
