The Sea & Sea YS-D2 strobe is setting new standards for features and power in a very versatile underwater strobe. Auto-DTTL is available using fiber optic sync with most cameras and housings. The auto DS-TTL exposure compensation function allows subtle lighting control by adjusting the Light Level dial in DS-TTL mode. Powered by four AA batteries, in a redesigned battery compartment, the YS-D2 offers a maximum light output of guide number 32. Keeping with the same great performance specs as the YS-D1, the YS-D2 has added an audible tone providing TTL and ready light confirmation. The YS-D2 also features a faster recycling time, and a rear glowing colored panel with easy-to-adjust controls.
Electrical sync is also provided with manual control only.
When a wide beam is not necessary, the YS-D2 has a guide number of 32 with an 80x80 beam angle. For an even stronger circular 100x100 light output at a guide number of 24, mount the Diffuser 100. When a wide-angle lens is used, the diffuser 120 can be attached with a guide number of 22. These three beam angles can be selected in accordance with the photographer’s requirements.
The YS-D2 is the world’s first slave TTL strobe equipped with an exposure compensation (EV) control function
By controlling the actual flash light level, the strobe realizes accurate exposure compensation with EV value.
