This Aquatica housing for the Nikon D200 has a cast aluminum body that is anodized and coated with polyurethane powder paint then clear coated. It operates safely to a depth of 300' (90m).
The lens port has a positive bayonet mounting system, which leaves no doubt that your port is secure in place and watertight. The bayonet system also offers fast access to lenses for rapid changing and there is a lens release button on the front of the housing to facilitate easy lens changes. The housing allows use of lenses ranging from Fisheye to the 200mm Macro.
The Aquatica D200 housing uses a viewfinder that derives a big and bright image and full frame viewing to your eye. LCD information in the camera's viewfinder is easily referenced while shooting, and chromatic aberrations have been significantly reduced for sharp focusing and exact composition.
Note: Requires lens port
Also Note: Most zoom lenses require Close-Up #3 diopter filter to correct focus distance.
