The YS-D2 is the most versatile underwater strobe available today.  The DS-TTL exposure compensation function enables subtle lighting control by adjusting the Light Level dial in DS-TTL mode.

Powered by only four AA batteries, the YS-D2 offers a maximum light output of Guide Number 32.

Its even and flat beam is suitable and powerful enough for professional use.  Not only is the YS-D2 suitable for wide-angle photography, it is also ideal for macro photography which requires delicate light level control.  The strobe's guide number can be reduced to 1.  Highly versatile, the YS-D2 offers more automatic and manual control over lighting to get that perfect exposure.  The YS-D2 is the most versatile underwater strobe available today.  The DS-TTL exposure compensation function enables subtle lighting control by adjusting the Light Level Dial in DS-TTL mode.

TTL with exposure compensation (EV) control function.

By controlling the actual flash light level, the strobe realizes accurate exposure compensation with EV value. Regardless of a compact or a SLR camera, you can achieve any desired exposure compensation. However, many TTL systems are not reliable.  The YS-D2’s DS-TTL exposure compensation function allows users to adjust the light level in TTL mode (-1.5EV, -1EV, -0.7EV, -0.3EV, +0.3EV, +0.7EV, +1EV, +1.5EV).

Two Accessory Diffusers

In macro photography when a wide beam is not necessary, no diffuser should be attached.  When both strong light output and a relatively wide beam are necessary, the diffuser 100 should be attached.  When a wide-angle lens is used, the diffuser 120 should be attached.  Three beam angles can be selected in accordance with the photographers's requirements.

Ergonomic Design

The YS-D2 will auto-sense when a sync cord is connected, causing the slave ON/OFF switch to no longer be active.  Simple controls and configuration enables easy operation.  The light level control clicks to aid in setting and operation.
