The D1H, designed for “action photography,” retains its predecessor’s 2.74-megapixel CCD, which captures 2,000 x 1,312-pixel images. But a larger memory buffer, new imaging algorithms and faster internal processing allow the D1H to shoot up to 40 continuous JPEG images at a rate of five frames per second (fps). It can also capture TIFF files.
The D1X features a 5.47-megapixel CCD imager, which captures interpolated 3,008 x 1,960-pixel (5.9-megapixel) JPEG or TIFF images. It can also capture smaller 2,000 x 1,312-pixel images or larger 16-bit images using Nikon’s optional Capture software.
Also equipped with a faster internal image processor, the D1X can shoot up to nine sequential JPEG photos at 3 fps. It has an ISO equivalency of 125-800, while the D1H has a wider ISO equivalency 200-1,600. The ISO ranges in both cameras are adjustable in 1/3, 1/2 or 1 EV steps. A new feature in both models is noise reduction, especially at the higher ISO settings.
Both models work with autofocus Nikkor lenses (using a Nikon F lens mount) and Nikon D-TTL compatible speedlights. However, Nikon D-type AF Nikkor lenses and SB-28DX and SB-50DX Speedlights offer the best performance, Nikon said.
The D1X and D1H start up faster than the D1, and use enhanced in-camera imaging algorithms to improve color, exposure and white-balance accuracy. Other new features include: a 2-inch color LCD screen with full-frame playback coverage and a white LED backlight for improved image viewing in bright light; an improved “multi-sensor” fill-flash algorithm; and user-selectable sRGB and Adobe RGB color-space modes.
In addition to providing a FireWire port for fast image uploads, the cameras support the 1GB IBM Microdrive (but not the older 340MB Microdrives), as well as CompactFlash Type I and II cards. An RS232C port allows connection of GPS units, which allow location data to be recorded in the header of image files.
Nikon expects to ship the D1X this spring for $5,500, followed by the D1H this summer for about $4,500. Each includes a magnesium camera body, neck strap, video cable, Nikon View 4 software, rechargeable battery and quick charger.
