Fit my sigma flash perfect, the only thing is the packaging stated it was for a canon flash, but once i put it on it fit perfect, and if it is pushed on properly, it’s nice and tight and definetly does it’s job and soften’s up that harsh light.
The Opteka flash diffuser 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 Opteka diffuser is easy to use and goes onto and off the flash in seconds with custom fitting and no 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.
