Nikon introduced on July 22 the Nikon D2H, a new professional model for reporters and action photographers.

This model has been drawn by Giorgetto Guigiaro "for a new series of digital devices". The Nikon D2H replaces the D1H bringing an update of the existing functions and new possibilities.

The Nikon D2H has, like the Canon 1D, a 4.1 megapixel sensor which seems to be well suited to the current needs of reporters and action photographers. Among these main characteristics:

• Possibility; to take 40 consecutive views in jpeg to 8 frames/second. 60% faster than the D1H,

• Autofocus on 11 zones by the Multi-CAM2000 module covering 75% of the image,

• 37 ms trigger time (versus nearly 80 ms for an F5)

• Magnesium case lighter and more compact than the previous ones and the competition, new Ion/lithium battery, anti-drip and with discharge. orientation detector,

• Viewfinder covering virtually 100% of the frame and complete with indications of white balance, size and quality. picture, ISO etc.

• Large rear screen of 6.4 cm (2.5 inch) and 210,0000 pixels.

• New white balance and improved color management,

• New i-TTL flash mode, wireless, with flash Nikon SB-800,

At PMA 2005 Nikon upgraded the Nikon D2H to Nikon D2Hs which features improvements made by the D2X (235,000 pixel screen, Wifi g, USB 2, etc.) and now allows you to take 50 consecutive shots in jpeg, or 40 in RAW from 8 frames/second.

Nikon has presented to the Photokina 2004 the Nikon D2X which uses the same box tier than the Nikon D2H but offers a new CMOS sensor, developed probably by Sony and not by Nikon, which allows the choice of a frame rate of 5 frames per second with 12.4 million effective pixels, ideal for the studio, or 8 frames per second with 6.8 million effective pixels. In the first case the coefficient/135 is 1.5, in the second 2 which transforms a 300mm/2.8 into 600mm/2.8.

The Nikon D2X is indeed a versatile camera valid both for studio photographers with its 12.4 million pixels and for sports photographers. So it can replace a Nikon D2H.
Compared to the Nikon D2H, the D2X has some improvements:

• 3D matrix measurement type 2

• New rear screen 6.4 cm diagonal and 235,000 pixels (instead of 210,000) with color histogram display

• 11-zone autofocus

• New image processing algorithms to improve color and contrast and high and low light

• sYCC profile

• GPS data entry

• USB 2.0 Enhanced

• Improvement of the ergonomics of certain commands

• Using WT-2.

The sensor's effective 4.1 megapixel image resolution and size, 23.1 x 15.5 mm, matches well with lenses attached to the D2H body.
This new Nikon exclusive LBCAST detector with JFET detector appears to be CMOS sensor type technology but with three layers instead of four.
This Nikon sensor project must be quite old since it is the result of R&D efforts started about ten years ago.

This sensor allows reduced power consumption and simultaneous reading of the 2 data channels of each pixel. It thus eliminates the need for a noise correction before the recording of the image and thus allows a fast saving and the use of WiFi module for the transmission of these images.
