The Omni-Bounce OM-EV from Sto-Fen for the Canon 270EX flash, creates a diffused bare bulb effect, providing even coverage across the entire picture. It is recommended for use with lenses from 15mm to 200mm in the 35mm format, but will work with other formats. The Omni-Bounce is easy to use and goes onto and off of your flash in seconds with custom fitting, except UNI, and No Velcro. It is quite durable and it is small enough to fit easily into your gadget bag or pocket.
