Dive into underwater photography with our most compact true TTL camera system. The Compact Digital housing is high quality, extremely durable, and backed by Ikelite"s long-standing reputation for excellence. Proprietary conversion circuitry allows two-way communication between the camera and Ikelite Substrobes providing true Panasonic TTL exposure. In addition to providing the most accurate automatic exposure, this ensures a faster recycling time and longer camera battery life as compared to fiber optic TTL systems. Take advantage of this powerful feature by attaching any current model Ikelite DS Substrobe. All camera controls except the Flash Open Switch are fully functional through the housing and depth rated to 200ft (60m). Two 12-24 threaded mounts on the bottom of the housing allow for the secure attachment of optional trays and lighting accessories.
