The Nikon D2H is a professional-grade digital single-lens reflex camera introduced by Nikon Corporation on July 22, 2003.[1] It uses Nikon's own JFET-LBCAST sensor with a 4.1 megapixel resolution. In 2005, the D2Hs refined and replaced the D2H, adding new features developed with the flagship D2X Digital SLR. The D2Hs was discontinued after the introduction of the D300 and D3 models.
Like most Nikon Digital SLR cameras, it uses a 'DX Format' sensor, which applies a crop factor of approximately 1.5x.

[edit] D2Hs improvements
The D2Hs was announced February 16, 2005 to replace the D2H Digital SLR camera, and added several improvements to the design.[2] Although the same sensor from the original D2H is used in the D2Hs, 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 reports 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.
GPS support and improved wireless support (with WT-2 transmitter for 802.11b/g), were improvements over the old D2H. A new LCD screen of the same size but increased resolution and flicker free was added to the body. The screen's playback mode now supports 15x zoom instead of the 8x of the D2H, with RGB Histogram.
The menus have been expanded to include an additional 5 languages for a total of 10. Like the new flagship D2X, it features a recent settings list, world time function, and modified vertical shooting buttons and CompactFlash card door opening.
The D2Hs features a continuous burst rate of up to 8 frames per second, with a buffer capacity of 50 JPEG files or 40 NEF (Nikon Electric Format- Nikon's proprietary Camera RAW image format) files. The 4.1 megapixel sensor has an ISO sensitivity equivalency of ISO 200-1600, in 1/3, 1/2, and 1 stop increments, as well as Hi-1 and Hi-2 ISO boosts (3200 and 6400 equivalency).
It offers full compatibility with AF-S, VR, DX, D and G type AF-Nikkor lenses, all functions except autofocus and some exposure modes with D-type Manual Focus Nikkors, with AI-P Nikkors all functions except 3D Color Matrix Metering II, 3D Multi-Sensor Balanced Fill-Flash and AF possible.
The D2Hs, like the D2X, offers compatibility with Non-CPU AI Nikkor lenses, which are usable in aperture-priority or manual exposure mode with Matrix-Metering, Center-Weighted and Spot metering available.
[edit] Reaction to Improvements over the D2H
Although the D2Hs has been considered by some to be obsolete from its very introduction due to its 'low' resolution[citation needed], the D2Hs has a reputation for extremely high image quality and excellent detail rendition[citation needed].
It is commonly used for many resolution-intensive applications[citation needed].
It offers a noticeable improvement over the D2H in overall image quality[citation needed]. Many users have reported that color rendition is improved, while the camera manages to offer a great improvement in noise at high sensitivities versus the D2H[citation needed]
Improvements are only seen in JPG. Raw files are indistinguishable between D2H and D2Hs.
