The Ikelite Digital SubStrobe DS-51 was created specifically for use with digital cameras because of their use of preflash metering, but it is completely compatible with all film cameras and film camera housings.
The DS-51 offers 50 watt-seconds of power in a compact size with coverage adequate for lenses as wide as 28 mm, or add the included diffuser for wider coverage and softer lighting. Combine multiple strobes to cover very wide angle lenses with minimal illumination of particles suspended in the water.
The DS-51 operates TTL when connected by an appropriate sync cord to some Ikelite housings. Alternatively, the DS51 provides a manual exposure mode with six manual power settings in one-half f-stop increments for precise illumination of subjects.
When connected to the Manual Controller, The DS-51 provides ten power settings in half/stop increments. The Manual controller can operate as a wireless sensor triggered by the cameras built in strobe or another strobe, or it can be connected by one of the Ikelite sync cords.
The Ball Arm System allows easy strobe placement from macro close-up to wide angle without changing aim of the Sensor.
This is a Complete SubStrobe package for use with Ikelite or Original Manufacturers digital camera housings. In the case of an original manufacturer housing, the IK9523.01 tray and handle needs to be purchased to mount the strobe arm system.
