The Gary Fong C4 Lightsphere II Inverted Dome Flash Diffusion System (Frosted) - for Canon 580EX, Sony HVL-F32X & Vivitar 730AF Flash Units is a large, round, soft and flexible diffuser that slips over the front of compatible flash units. The inside of the Lightsphere is completely textured to make the light dispersion even more "soft" than it would be otherwise. And because of this design, it is possible to make the material more translucent, keeping the unit from losing a lot of light while actually increasing the diffusion and softness of light.
An opaque color has been added to the inside of the Cloud version, and this "frosted" version creates an even softer effect, which makes it ideal for close-ups, portraits, and event photography.
The included inverted dome allows you to softly diffuse direct light with a large, soft source without creating flare on the front of your lens.
