The D90 is one of the more affordable DSLRs in the Nikon lineup. With this model, excellent camera features are brought within the reach of more amateur photographers.
The camera boasts of a 12.3-megapixel CMOS imaging sensor in DX format. This, together with its EXPEED image processor and Nikkor lens, assures you of high-resolution images with minimum noise. One of its best features is that it is the first DSLR with an HD movie capability. It can capture 24 fps movie clips at 720p HD complete with sound.
In order for recreational divers and water adventurers not to miss out on the opportunity to record their exploits with the Nikon D90, Aquatica introduced the AD90 Underwater Housing that is dedicated to the D90, and which is equally affordable.
Known formally as the Aquatica AD90 Underwater Housing for Nikon D90, it is constructed from a solid piece of machined aluminum that resists twisting and warping. This is a necessary feature as twisted or warped controls could fail to function especially when subjected to high water pressures. The aluminum is anodized and coated with polyurethane for extra protection against corrosion resulting from exposure to salt water.
All controls for taking stills and videos are accessible through its buttons and levers. Both the on/off/info and shutter release levers are extended for an easier operation even when wearing gloves. Its bayonet port system accommodates various ports, extensions, and gears. It also has a lens release button allowing you to change lenses through the port aperture.
Picture composition can be done either through Aquatica’s Aqua View Finder which magnifies the image from the camera viewfinder, or through its LCD monitor which is visible through a window in the back of the housing.
The housing has a depth rating of 300 feet or 90 meters.
