Ikelite 6812.7 iTTL Underwater Housing for Nikon D700

This Ikelite 6812.7 iTTL Underwater Housing for the Nikon D700 allows iTTL operation with the Ikelite DS digital SubStrobes when connected to the housing's bulkhead by a sync cord. A large dial on the back of the housing puts precise exposure control right at your fingertips. The top (yellow) half of the exposure dial provides four 1/3 f/stop increments over or under flash compensation to be added to or subtracted from any compensation entered into the camera. The bottom (black) half of the dial provides seven manual power settings in half-stop increments. Other manufacturers' strobes can be used, but they cannot provide iTTL exposure or be adjusted manually through the housing.
