* When the YS-03 is used with a non-SEA&SEA housing, a Strobe Mask Set may be required along with the Fiber-Optic Cable.

* Use of genuine SEA&SEA Fiber-Optic Cables is recommended. SEA&SEA strobes may not function properly if third-party Cables are used (functions such as TTL auto exposure in particular).flash, it is not necessary to manually adjust output. The YS-03 is compatible with any camera with a pre-flash.

* Comes with diffuser as standard.

* The half-translucent section diffuses and softens the light from the strobe. Using the diffuser gives softer, more evenly exposed images. The diffuser will also help reduce effects of overexposed images or when strong light produces shade/shadow in the image.
