Nikon has just announced their latest flagship FX-format digital SLR camera, which is known as the Nikon D4S. This particular shooter (doesn’t the naming convention somewhat remind you of the iPhone, with the iPhone 4 and iPhone 4s, followed by more of the same with the iPhone 5 and iPhone 5s?) will be based on the Nikon D4, where the D4S is capable of responding in a far more complete manner to what professional photographers love, delivering revisions to a range of features and functions, where among them include AF performance, image quality, workflow and operation, in addition to movie recording.
In fact, the algorithms that have been used by the AF system have been specially refined for a greater degree of accuracy and versatility, where the autofocus itself has been initiated faster, allowing it to keep pace with the intended subject. Single-point AF, Dynamic-area AF, 3D-tracking, and Auto-area AF will be joined by a fifth AF-area mode that is simply known as Group-area AF, where it relies on 5 focus points. This opens the door to smoother autofocusing as well as a faster workflow.
Sporting a new EXPEED 4 image-processing engine, a new Nikon FX-format CMOS image sensor that does 16.2MP photos, ISO 100 to ISO 25600, as well as support for extended sensitivities as low as the equivalent of ISO 50 and as high as the equivalent of ISO 409600, the Nikon D4S is not going to come cheap at $6,500 a pop when it arrives later this March 6th. Looks like rumors of an end February announcement for the Nikon D4S were spot on.
