The Sto-Fen OM-EW 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 equal in
other formats as well). The Omni-Bounce is easy to use and slips onto
and off the flash in seconds with custom fitting and no need for touch
fastener. Designed for years of service without the bulk of some other
diffusers, it is small enough to fit easily into a gadget bag or pocket.
