Nikon D4 is finally out, next-generation flagship Nikon digital-SLR camera features 16.2-million pixels FX-format CMOS image sensor and EXPEED 3 image-processing engine, image sensor supporting an incredible range of sensitivities from ISO 50 to ISO 204800, The 51 focus point AF system has been improved with faster initiation of autofocusing and the ability to detect and focus on subjects with less lighting. In addition, 11 focus points are fully functional when lenses with a maximum aperture of f/8 are used. 11 focus points are fully functional when lenses with a maximum aperture of f/8 are used. All of this means more precise autofocusing when super-telephoto NIKKOR lenses are used with teleconverters (2.0x).
A dedicated movie-record button has been positioned near the shutter-release button for smooth starting and stopping of movie recording with a feel similar to that of still-image shooting. Full-HD movie recording at a frame size of 1920 x 1080 and frame rate of 30 fps is supported, and the H.264/MPEG-4 AVC video compression method has been adopted. Movies up to 29 minutes 59 seconds can be recorded. Image sensor sensitivity begins at ISO 200 and can be expanded to the same ISO 204800 equivalent possible with still-image shooting.

·Other D4 functions and features
- Extremely durable shutter that has passed testing for 400,000 cycles
- Magnesium alloy adopted for the very strong, durably body that is very resistant to dust and water
- Effective sealing using O rings and packing make the camera more resistant to dust and water
- Silent shutter-release mode for live view photography that almost completely eliminates the sounds of the mirror and shutter operation
- A time-lapse photography feature, with which the camera automatically takes photos at selected intervals to record a time-lapse movie, which can be played back at 24–36,000x normal playback speed
- Operation optimized for both horizontal (landscape) and vertical (portrait) shooting
- Button backlights (illuminators) for increased visibility when working in dimly lit or dark situations
- High-performance viewfinder, utilizing a glass pentaprism, with a frame coverage of approximately 100% (FX format) and magnification of approximately 0.7x
- Four image area options for still shooting—FX (36 x 24), 5:4 (30 x 24), 1.2x (30 x 20), DX (24 x 16)—with viewfinder indicator that identifies the current image area
- A 3.2-inch, approximately 921k-dot LCD monitor with reinforced glass and wide viewing angle; integration of the glass and panel reduce internal reflections
- A virtual horizon that shows the degree to which the camera is tilted sideways (roll), forward or backward (pitch) with display in the monitor and viewfinder
- White balance that can be adjusted in units of 10 K; white balance can be specified separately for shooting (white balance applied to images) and monitor display with still-image shooting in live view mode
