Nikon D2H
Encyclopedia
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. In 2005, the D2H was replaced by the D2Hs, which added new features derived from the 12 megapixel 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

ing 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.
GPS support and improved wireless support (with WT-2 transmitter for 802.11b/g) were also added. A new LCD screen of the same size but with increased resolution and a higher refresh rate 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 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.
Although the D2Hs has been considered by some to be obsolete from its very introduction due to its relatively low 4.1 megapixel resolution, the D2Hs has a reputation for extremely high image quality and excellent detail rendition.
The D2Hs offers a noticeable improvement over the D2H in overall image quality and many users have reported that color rendition is improved in JPEG files (raw is the same), while the camera manages to offer a great improvement in noise at high sensitivities versus the D2H
(IR) filter, causing certain dark-colored fabrics to take on a slight magenta color cast. Skin tones may also appear slightly ruddy. Use of a No. 486 digital UV/IR blocking filter can help resolve the problem with lenses that are at least 50 mm or longer. Lenses shorter than 50 mm are not recommended for use with a No. 486 filter due to a tendency for the corners of the image to take on a cyan color cast.

Crop factor
In digital photography, a crop factor is related to the ratio of the dimensions of a camera's imaging area compared to a reference format; most often, this term is applied to digital cameras, relative to 35 mm film format as a reference. In the case of digital cameras, the imaging device would be a...
