A new full-frame, 16.2-megapixel CMOS image sensor combines with new EXPEED3 processing to provide a normal ISO range of 100-12,800 (expandable to 50-204,800), plus shooting rates of 10 fps with AF for each shot or 11 fps with focus and exposure locked at the first frame. The AF system still has 51 points, but is faster and more responsive, and now works with lenses or lens/converter combos as slow as ƒ/8. A new metering system features a 91,000-pixel RGB 3D Color Matrix Metering III sensor and Nikon's advanced SRS (Scene Recognition System).
The D4 can shoot 1080p full HD video at 30 fps and 24 fps, and 720p HD at 60 fps and 30 fps, in MOV format with H.264/MPEG-4 AVC compression and full-time Servo AF, if desired. Like the new D800, the D4 can stream uncompressed full HD video to an external monitor or recording device. You can record video in full-frame, DX (APS-C) or 2.7x crop modes, all with 16:9 full HD resolution. A built-in microphone records mono sound, or an optional external stereo mic can be used. The D4 can do time-lapse at 24-36,000X, saving the images as a video file.
You can use pretty much all F-mount Nikon lenses for still and video photography with the D4, the AF-S and AF-I G and D lenses providing all camera features. When a DX lens is used, the camera automatically crops to DX format (6.8 megapixels) to avoid vignetting. (The D4's chief rival can't use its manufacturer's APS-C lenses at all.)
STANDOUT FEATURE: Can shoot up to 11 fps at 16.2 megapixels.
