In February 2014, Nikon announced a new flagship DSLR, the D4S. Below, you'll find a little more information about this technological beast. Their press release says it accommodates the needs of "...professional photographers who sometimes find themselves working under quite severe conditions". Just to clarify, as an amateur photographer, we too also sometimes find ourselves working under quite severe conditions, e.g. in the last year I've been photographing Snow Leopards at altitude in the Himalayas, and the Northern Lights in the middle of a frozen lake at midnight. Both were colder than -25 degrees Celsius at times! Anyway, back to the camera!
Autofocus
Key for any wildlife or sports photographer is autofocus behaving quickly, and predictably, even if the subject isn't! The D4S has enhancements compared to its D4 predecessor, with faster initiation, plus a new 'Group Area AF', using five autofocus points, one specified by the photographer.
Image processing
"The new EXPEED 4 image-processing engine, a new Nikon FX-format CMOS image sensor, and an effective pixel count of 16.2-million pixels...", accompanied by an ISO range from 100-25,600 (extendable to a massive range of 50-409,600) ensure that image you capture is processed quickly and accurately.
Movie recording
The D4S supports a "frame size of 1920 x 1080 with a frame rate of 50p or 60p", with various enhancements to improve the quality of the recording.
Additionally, there are improvements to LAN connectivity, a redesigned grip and a 12-bit RAW format.
