Dive into underwater photography with this 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 Nikon 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. See the "External Underwater Strobes" section for complete details. All camera controls except Fn (FUNC) Button, Lens Ring Release Button and Diopter Adjustment Control are fully functional through the housing and depth rated to 200ft (60m). The included tray and release handle offers balance and exceptional handling while providing a convenient attachment point for optional Substrobe mounting arms. Strobe arms can be released easily at the touch of a button whether above or below water. The optional Dual Handle and Tray assembly #9523.32 provides even greater stability and allows for the addition of a second Substrobe.
