The Nikon D810 DSLR Camera takes its place as the high resolution option in the Nikon DSLR lineup. It features a 36.3MP FX-format CMOS sensor without an Optical Low Pass Filter for particularly sharp and detailed still imaging. With the addition of the EXPEED 4 Image Processor, performance speed is increased compared to the EXPEED 3 and noise is effectively reduced throughout the ISO range. Continuous shooting speed in FX format is 5 fps and in DX format hits a maximum of 7 fps. In addition, the full HD video capabilities of the D810 have been upgraded to include 1080p capture at 24, 30 and 60 fps. Also, the improved efficiency of the processor enables up to 1200 shots on one battery charge and 40 minutes of video recording. Low light performance has been upgraded thanks to a wide native ISO sensitivity range that runs from 64 to 12,800 and can be expanded from 32 to 51,200.

The advanced Multi-CAM 3500FX autofocus sensor offers 51 AF points with 15 cross-type sensors and Group Area AF enables five AF sensors to be used as one group. This is useful when shooting subjects that cannot be tracked easily by one AF point due to lighting conditions.

As a camera optimized for video capture, the D810 features recording in both FX and DX formats including simultaneous recording to memory cards and an external recorder as well as recording 60p output to an external recorder. The ISO range for video has also been expanded to run from ISO 64 to 12,800 and expand to 51,200. Automatic ISO adjustment in manual mode enables smooth exposure transitions. A built-in stereo microphone is supported as are jacks for an external mic and headphones. A selectable audio frequency range provides exacting control over sound recording.

A 3.2" LCD with 1,229K-dot resolution provides playback viewing and live view, and improved coatings on the optical viewfinder components provide brighter images and more accurate colors. Live View function now includes split screen display zoom for stills, and zebra highlighting display in video mode. Full aperture metering during live view for still shooting is supported.

Interval and time-lapse shooting feature exposure smoothing, and the maximum number of images per sequence is now 9,999. Improved Picture Control settings now offer Flat Picture Control to enable maximum dynamic range and color adjustments in post-production.

The D810 utilizes dual media slots for both Compact Flash and SD cards, and it provides a built-in flash with i-TTL metering as well as a hot shoe mount. A larger grip enables comfortable control for extended shooting, and a secondary "i" button has been added to back panel for faster access to important settings.
