TTL Flash Exposure
Connection with a TTL sync cord is the most reliable and efficient way to fire an external underwater strobe. The camera's built-in flash does not need to fire, providing the extended battery life and zero lag time between exposures. Our proprietary circuitry allows direct communication between the camera and current Ikelite DS Substrobes* for the most accurate through-the-lens (TTL) metering control of an off-camera flash. Electrical bulkhead and TTL circuitry are provided standard and included in the base purchase price.
No more fiddling with tiny hard-to-read knobs. Exposure settings of a DS Substrobe can be viewed and adjusted quickly using two simple pushbuttons in theback of the housing. TTL mode provides four half-f/stop increments over or underflash compensation to fine tune exposure. Or control strobe output completely through the back of the housing using one of the 8 manual power settings provided in half-stop increments.

Ergonomic handling
Controls are provided for all important camera functions. Shutter, video recording start/stop, and a large zoom control knob can all be comfortably reached without removing your hands from the handles. Comfortable rubberized grips provide quick-release attachment points for strobes and accessories. The try and handles may be removed from the housing for convenience in traveling. The complete housing is neutral or slightly negative in freshwater depending on choice of lens port.

Clearly Superior Design
A clear view of the camera and o-ring seals facilitates easy assembly and operation. Heavy-duty polycarbonate construction is durable and corrosion-free to ensure performance in even demanding conditions. Lens ports can be removed and replaced quickly with a simple positive locking system which provides visible assurance when the housing is assembled properly.
