Nikon D2H SLR Review
By Movable Type Admin
AF Nikkor Lens Mount
The D2H is compatible with about 90% of the F mount Nikkor lenses made. You need to use a
focal length conversion factor of 1.5x to determine the picture angle compared
to the 35mm format.
On the left side of the lens mount is the Depth of Field (DOF) preview button and the FUNCtion button (by default it locks the flash value but can be set to other functions in the custom menu), on the right side is the lens release lock button and the focusing mode switch (Manual, Single AF or Continuous AF).
AF-S Nikkor VR 24-120mm f/3.5G ED
New Nikkor DX Lenses
Nikon introduced two new wide-angle lenses designed exclusively for Nikon digital SLR cameras that feature Nikon's DX Format Sensor. The new AF DX Fisheye-Nikkor 10.5mm f/2.8G ED lens and the AF-S DX Zoom-Nikkor 17-55mm f/2.8G IF-ED lens significantly expand Nikon's DX-Nikkor category of interchangeable lenses, and follow close on the heels of the recently introduced AF-S DX Zoom-Nikkor 12-24mm f/4G IF-ED lens. These three new DX-Nikkor lenses now offer Nikon digital SLR photographers the broadest wide-angle coverage available for digital SLR cameras, while significantly enhancing lens performance by optimizing them for digital cameras.
Nikon engineers determined that by reducing the diameter
of the lens' image circle (the image it projects on the DX format sensor), a range of
lenses with practical size and excellent performance could be developed. Originally
designed to address the market's need for wider angle-of-view, high-performance optics for
digital SLR photography, DX-Nikkor lenses offer advantages of compact and lightweight
design, fast aperture and fast autofocus through Nikon's Silent Wave Motor design. By
optimizing them for Nikon's DX-format image sensors used in all Nikon D-series digital
SLR's, these lenses achieve outstanding center-to-edge-to-corner image quality. All
DX-Nikkor lenses are compatible with all Nikon D-series digital SLR cameras, including the
D1, D1X, D1H, D100 and the D2H.
AF DX Fisheye-Nikkor 10.5mm f/2.8G ED
At 180° diagonal angle-of-view, the new AF DX Fisheye-Nikkor 10.5mm f/2.8G ED is not only the world's first fisheye lens designed for digital SLRs, but also the first to offer such a wide picture-angle for any digital camera. It features optimized optical performance with close range focusing up to a mere 5.5 inches for extreme close-ups. Innovative Close-Range Correction (CRC) technology ensures consistently crisp, sharp images. This palm-sized lens is small and lightweight, and its compact design is exemplary of the potential of DX-Nikkor to reduce lens size and offer added convenience to Nikon digital SLR users.
While photographers will enjoy the incredible depth of field and unique perspective characteristics of this fisheye lens, they can also double it as an ultra-wide angle lens using Nikon Capture 4.0 software's unique 'Fisheye-to-Rectilinear Image Transformation' capability. With the click of a button, Capture 4.0 instantly transforms fisheye images taken with this lens into straight lined, rectilinear images. The software offers a choice of cropping the image vertically or horizontally, during the transformation process, and gives an outstanding 110° angle-of-view when oriented horizontally.
AF-S DX Zoom-Nikkor 17-55mm f/2.8G IF-ED
Set to become the standard lens for Nikon digital SLR users, the AF-S DX Zoom-Nikkor 17-55mm f/2.8G IF-ED offers the widest (3.2x) zoom range in its category, with a broad 79°- 28°50' angle-of-view. Consistent with DX-Nikkor design, the lens is compact and lightweight, while offering a fast f/2.8 constant aperture. The AF-S DX Zoom-Nikkor 17-55mm f/2.8G IF-ED provides excellent versatility from wide-angle through standard and medium telephoto shots, making it ideal for a diverse range of picture taking situations.
The lens incorporates three ED (Extra-Low Dispersion) glass elements and three aspherical elements in a 14-element, 10-group construction. The lens also features Nikon's innovative Silent Wave Motor (SWM) technology that is highly regarded by professional photographers for its ultra-quiet operation and fast autofocusing with superior accuracy.
Both new DX Nikkor lenses exhibit enhanced performance with extremely low coma and lateral aberration, along with improved MTF (Modulation Transfer Function) curves, when compared to other lenses in their categories. They feature
Nikon's high-performance Super Integrated Coating for superior color reproduction and minimized ghost and flare.
AF-S VR Zoom-Nikkor 200-400mm f/4G IF-ED
The AF-S VR Zoom-Nikkor 200-400mm f/4G IF-ED lens with advanced Vibration Reduction (VR) technology and Silent Wave Motor technology is designed for news, sports/action, wildlife and nature photographers, this innovative lens is based on a new optical system that features four ED glass elements.
The VR technology in the AF-S VR Zoom-Nikkor 200-400mm lens offers users a choice of either Normal or Active mode. Normal mode detects camera shake when the lens is hand held and the photographer is on a stable base. The Active mode goes a step further to detect vibration caused by photographing from a moving platform, such as a car or a helicopter. Its VR system is smart enough to detect a panning motion and correct vibration on the vertical axis.
In addition to VR technology and ED glass elements, the AF-S VR Zoom-Nikkor 200-400mm lens includes a selection of Nikon advanced technologies such as Manual/Automatic mode, Silent Wave Motor Technology (SWM) and G-Type design (aperture control exclusively from camera body).
Offered exclusively in Nikon's AF-S optics, the Manual Automatic mode (M/A) allows for instant switching between autofocus and manual focus, virtually eliminating lag time in the transition and enabling photographers to make a last minute adjustment, even if the autofocus system has locked onto the subject.
This performance is complimented by Nikon's automatic Focus Tracking with Lock-on, a technology that will enable the system to maintain sharp focus even if the subject is momentarily obscured from view, or if the camera's AF sensor momentarily moves off the main subject.
The AF-S VR Zoom-Nikkor 200-400mm lens also features Nikon's Silent Wave Motor technology. This innovative technology is highly regarded by professional photographers for its silent and fast autofocusing with superior accuracy and ultra-quiet operation. This technology is exclusive to Nikkor optics and is incorporated in a large assortment of lenses that bear the AF-S mark.
