Sea&Sea YS-D130R RC DS-TTL Strobe

Illuminate the ocean as it was meant to be seen.

Natural, sunlight-like illumination that reveals the true colors of fish, coral, and the ocean.

Circular flash tube for even illumination

For the first time since the YS-250PRO, the YS-D130R features a newly designed circular flash tube combined with a dedicated reflector, delivering stable and uniform light output.
The smooth, evenly diffused circular beam illuminates your subject without harsh hotspots, producing soft, natural shadows and beautifully balanced lighting across the entire frame.

When shooting close to marine life, the circular catchlight appears naturally in the subject’s eyes, adding depth, expression, and a lively presence for stunning underwater portraits.

One of my favorite summer pleasures in Hakodate is spending time with the “mimi-ika,” a tiny species of bobtail squid. As the moment of hatching approaches, the little squid inside their eggs repeatedly shift their coloration—from dark to pale and back again—quietly preparing for the world outside.
And those two circular flash tubes you see on either side of the eggs? Unlike traditional linear ones, their round shape blends more naturally into the scene, even when they appear in the photograph. It’s a subtle difference, but one that feels unexpectedly welcome.

Natural and Soft Light

The YS-D130R is designed with a color temperature of 5600K, closely matching natural daylight.
Higher color temperatures produce cooler, bluish tones, while lower values create warmer, reddish hues—5600K delivers a perfectly balanced, natural look.
By applying an amber coating to the flash tube, the YS-D130R produces light that is both soft and natural, closely resembling sunlight underwater. Additionally, while diffusers typically alter color temperature, the YS-D130R’s dedicated diffuser is specially engineered to maintain consistent color fidelity, ensuring stable and natural lighting in every shot.

Features RC Mode officially certified by OM Digital Solutions Corporation

The YS-D130R supports RC Mode of the OM SYSTEM Wireless RC Flash System by OM Digital Solutions. Flash output can be precisely controlled via digital light signals from the camera, enabling accurate exposure control. When paired with a compatible camera, this feature provides a more comfortable and seamless underwater shooting experience.
