Ikelite 4044.1 Underwater Camera Strobe DS51

The Ikelite Digital Sub Strobe DS-51 was once created specifically to be used with digital cameras as a result 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 more than one 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 a few Ikelite housings. On the other hand, the DS51 provides a manual exposure mode with six manual power settings in one-half f-stop increments for precise illumination of subjects. For even more precise keep watch over the DS-51 will also be connected to The Manual Controller. This provides ten power settings in half/stop increments. The Manual controller can operate as a wireless sensor triggered by another strobe, or it may be connected by one of the most Ikelite sync cords.
