Sea & Sea TTL Converter, Connects Housings for Canon Cameras with YS-250PRO Strobes.

The Sea & Sea TTL allows TTL exposure control when connected to Sea & Sea housings for Canon digital SLR cameras with the Sea & Sea YS-250PRO strobe. The converter allows quick switching underwater between TTL mode and manual mode from outside the camera. After checking the results of a shot in the LCD monitor, use the TTL correction dial to adjust the amount of strobe light for the next shot. Because the converter comes with two top mounted strobe connectors, you can use advanced automatic TTL flash adjustment with two strobes.
