This Nimar NI303D underwater housing is designed for the Nikon D40 and D40X digital SLR cameras. With this housing you can create amazing images as you explore the underwater realm down to a depth of 200' (60m). The housing is sized and weighted for near-neutral buoyancy and superb handling underwater. The enlarged optical viewfinder provides enhanced viewing even while you are wearing a diving mask.
Camera installation is quick and simple, and the O-ring seal can be checked visually through the clear polycarbonate housing. The locking system consists of secure hooks on every side of the housing. This prevents the housing from accidentally opening up. In case there is a problem and water enters the housing, the included moisture alarm gives you enough warning with a flashing light and an audio alarm to exit the water before the camera becomes damaged.
The housing includes a free 3W LED focusing light. This provides enough light so your camera's autofocus system works properly. It is also ideal for night dives, inside shipwrecks, or caves. A mounting bracket for the housing is included, as well as a strap that allows the light to be handheld or mounted on ones hood or helmet.
An external strobe is recommended to bring back the natural colors of your subject and to reduce the illumination of particles suspended in the water. This form of aquatic light pollution is called backscatter. When the optional Nimar strobe is connected to the housing's bulkhead, you will get the convenience of automatic TTL exposure control. Other manufacturer's strobes can be used in manual mode only.
The housing features a bayonet-mount interchangeable lens-port system. The standard polycarbonate zoom port for the standard Nikon kit lens is included with the housing. Other polycarbonate and optical glass ports for the use of most macro, wide-angle, and zoom lenses are available.
