Let’s just throw down some specs, then get to pricing, release date, and then the press release.
The Nikon D4 is the successor to the D3 (which debuted 5 years ago), whereas the D3S was sort of an improvement or spin-off. It has a 16.2 megapixel sensor, higher ISO (204,800 at Hi-4), and a brand new full-frame FX-format sensor. There’s 720/24p to 1080/30p video recording, as well as an impossibly high price tag of $5,999.95 when it launches in late February. But all the dough is worth the goods: there’s 91k-pixel RGB 3D Color Matrix Meter III built into the D4, which allows you to accurately examine color values and details of your photos, on top of the fact that the Nikon D4 practically has a night-vision mode. A 921k-dot 3.2-inch LCD, which offers a 170-degree viewing angle and ambient light sensor is also included to examine photos. And of course, let’s not forget the 51-point autofocusing system with a compatibility to nearly all Nikon lenses.
Full press release after the break.
