More information

The Nauticam NA-645DF Housing is designed with the photographer’s in water experience in mind. Careful design attention results in intuitive, convenient access to key controls (shutter release, f-stop, shutter speed, AE-L, and four digital back push buttons) from the housing handles.
The housing back is oversized to yield near neutral buoyancy and excellent front-back balance. Configured for the Phase One 28mm wide angle lens with a 9” glass dome port, the housing is perfectly balanced, and .7kg negatively buoyant. When set up with a flat port system and Phase One 120mm macro, the entire system is .15kg negatively buoyant.

Four mounting points are available for accessory strobes and lights. Two Nikonos, Ikelite, or S6 Flash connectors are included as standard equipment.

Lens ports are inserted straight into the Nauticam mount, eliminating the twisting or threading actions that can extrude dry o-rings. Once seated, the large red port lock lever is engaged, securely locking the port in place. To remove a lens port, the silver unlock button is pressed, the port lever rotated to the outer position, and the port is pulled straight out of the housing.
