alderman gable: Nikon announces D4 DSLR camera: full-frame 16.2 MP sensor, 204,000 extended ISO, $6,000 price tag

More than two years after the D3S began shipping and roughly a half-decade after we first got a peek at the D3, Nikon has finally announced the full-frame DSLR's long-awaited successor. As expected, the Nikon D4 boosts both megapixel rating (to 16.2) and extended ISO (204,800 at Hi-4), and includes a brand new full-frame FX-format sensor. Video capture also jumped from 720/24p to 1080/30p, but so did the camera's somewhat-out-of-reach price tag -- you'll be dropping $5,999.95 when the D4 hits stores in late February. You're clearly not spending all that hard-earned photo dough for nothing, though. There's also a 91k-pixel RGB 3D Color Matrix Meter III, compared to a 1,005-pixel meter in the D3S, enabling the camera to evaluate the color and brightness of a scene with much greater precision, yielding much more accurate results. And since the D4 reportedly offers phenomenal low-light performance, you'll probably be using it quite often in the dark -- letting you get good use out of the new back-lit controls.

Photographers can preview images using the 921k-dot 3.2-inch LCD, which offers a 170-degree viewing angle and ambient light sensor. HD video can be previewed on the display as well, or directly through the HDMI port, which also supports uncompressed 8-bit preview video output with optional overlay. Naturally, the D4 is fast. It can power on and be ready to shoot in approximately 0.012 seconds, and can capture 10 fps stills at full resolution with full auto focus and exposure. Willing to lock both AF and AE? The D4 goes to 11. A new 51-point AF system offers full cross-type focusing that's compatible with all Nikon lenses, even when paired with a teleconverter. The D4 includes two card slots with support for both UDMA-7 CF and the recently-announced XQD format, which brings write speeds of up to 125 MB/s -- enough to capture 105 consecutive RAW images at 10 fps. You'll find full details and specs on the D4 just past the break, along with an overview of Nikon's new AF-S NIKKOR 85mm f/1.8G FX-format lens, which is set to ship in March for $499.95.
