The Ray Flash (U.S. and international patents pending) is a unique adapter for your hot-shoe flash unit designed to replicate the lighting effect produced by traditional, expensive, and heavy powered studio ring light units. 

The Ray Flash is portable and lightweight, and has been designed to take advantage of a camera’s TTL metering capabilities.  Because the Ray Flash relies on the hot-shoe flash to generate its light, it contains no electronics, no flash tubes and requires no cumbersome cables.  The light distribution is accomplished through a sophisticated system of internal light-shapers designed to distribute and project the light evenly around the lens.  

The Ray Flash creates the distinctive ring light effect:  a three-dimensional shadow-wrapped look around the subject.  Because ring flash light originates from a circle around the lens, it produces a virtually shadowless look on the front of your subject, while producing a soft even shadow around the edges. The versatile Ray Flash is ideally suited for fashion, wedding, portrait, journalist and macro photography as either a main or fill light.

Weighing just 13-14 oz, the Ray Flash is lightweight and is easily supported by hot-shoe mounted flash units. The 4 1/8” internal diameter of the Ray Flash is large enough to accept almost all professional lenses from Nikon & Canon. 

The Ray Flash is specifically designed for the Canon 580EX (I & II), Nikon SB800 and Nikon SB900 flash units.  However, existing Ray Flash models will also fit older Nikon flash units, including the SB24, SB26 and SB600, as well as selected flash units from Sony, Metz, Olympus, and Sigma.

Exposure control:  

The Ray Flash does not interfere with a camera's TTL functions. 
Please also note that the Ray Flash does not change your flash's color temperature.
