Nikon D2H

The Nikon D2H is a professional-grade digital single-lens reflex camera introduced by Nikon Corporation on July 22, 2003. It uses Nikon's own JFET-LBCAST sensor with a 4.1 megapixel resolution, and is optimised for sports and action shooting that require a high frame rate.

Nikon added an improved light metering system, faster subject acquisition and tracking algorithms to the Multi-CAM-2000 Autofocus module, and expanded both the JPEG and RAW continuous shooting buffer.

Nikon also reported improved noise reduction at high sensor sensitivities. The ASIC image processing was changed to 12-bit from the original D2H 8-bit. Auto White Balance was altered with improved low color temperature lighting, mixed ambient, and speedlight lighting. SYCC color space was added, and Exif compliance was adjusted from Exif 2.2 to Exif 2.21, DCF 2.0, and DPOF.
