The Sto-fen Omni-Bounce OM-ET is a small and light flash diffuser specially designed for the Canon 600EX RT Speedlite. The Omni-Bounce creates a diffused bare-bulb effect giving even coverage across the entire frame, with lenses from 15mm to 200mm in the 35mm format (and equivalent in other formats as well.) The Omni-Bounce is easy to use and attaches to the front of your flash in seconds with custom fitting and no Velcro. Designed for years of service without the bulk of some other diffusers, it is small enough to fit easily into your gadget bag or pocket.
