The Optical YS Converter/N from Sea & Sea is an underwater photo accessory for TTL strobe syncing with the Nikon D7100, D7200, or D810 DSLR camera. This internal TTL converter fits within the Sea & Sea MDX-D7100 or MDX-D810 underwater housing and connects directly to the camera's hot shoe to enable rapid firing and reduced recycle time. It converts the camera's TTL signal into a light signal, allowing you to trigger the optional Sea & Sea YS-D1, YS-01, and YS-110a strobes using the Fiber-Optic Cable II.
