YS-D3 DUO Underwater Strobe
The red color is not shipping until December.
A limited amount of White YS-D3 Duo's is now currently available
The YS-D3 DUO is an underwater strobe specifically designed to be compatible with the Wireless RC Flash System of OM SYSTEM digital cameras. The RC System is a light control mode wherein the camera automatically regulates the flash output based on the brightness detected through the lens. This system utilizes a digital optical signal to achieve precise control over the light. surpassing the typical TTL mode found in most underwater strobes. It allows for fine-tuning of the light intensity through options such as flash/non-flash selection or manual operation.
The YS-D3 incorporates newly designed circuitry and a light-emitting unit. resulting in an impressive guide number of 33. To ensure even light dispersion from the center to the edge. a high precision aspherical optical triodal lens is fitted over the two flash tubes. By attaching the standard accessory Diffuser. the strobe's beam angle can be increased to 110°. Furthermore. when the optional Dome diffuser is used. the beam angle can extend as wide as 150° (to be determined).
To prevent any confusion. it's important to note that the YS-D3's guide number (GN) and beam angle are measured on land. not underwater.
Ships with Ball mount only.
