Nikon just announced the new D4s. Based on the D4, the D4S responds more completely with revisions to a number of features and functions, including AF performance, image quality, workflow and operation, and movie recording, adopted after running a variety of simulations of the functions required by professional photographers who sometimes find themselves working under quite severe conditions.

Autofocus has been improved for faster initiation, and is better able to acquire and track the intended subject. In addition to the four time-tested modes available with the D4 (Single-point AF, Dynamic-area AF, 3D-tracking, and Auto-area AF), the D4S offers a fifth AF-area mode known as Group-area AF (uses 5 focus points: one specified by the user, as well as one each above, below, to the left, and to the right of the selected focus point). This mode enables not only smoother autofocusing, but also a faster workflow with continuous shooting at approximately 11 fps* with AF and AE tracking

A new Nikon FX-format CMOS image sensor, has an effective pixel count of 16.2-million pixels.  The ISO has also been bumped up to a new range from as low as the equivalent of ISO 50 and as high as the equivalent of ISO 409600.  Thats just seems incredible.

The D4S supports movie recording at a frame size of 1920 x 1080 with a frame rate of 50p or 60p. EXPEED 4 enables rich tone reproduction, with very little noise, throughout the entire range of standard sensitivities (ISO 200-25600). Movies recorded at a 1920 x 1080 crop setting exhibit especially sharp and clear picture quality. 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.

Video Recording Capabilities:

  • D-Movie function for recording full-HD 1920 x 1080 60p/50p movies
  • 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).
  • 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.
  • The D4S responds to demands for movie recording with a variety of other capabilities as well, including the ability to change the image area in movie live view, and to enable Auto ISO Control for automatic adjustment of ISO sensitivity at a fixed shutter speed and aperture value.
  • The D4S also offers a new exposure smoothing function for time-lapse movie recording. This function smooths exposure between frames for less flicker in resulting movies.
  • 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 x 424/30 fps and 640 x 424/25 fps.
