Product Description

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.

Customer Reviews

great diffuser
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.

It's not a dedicated Sigma Diffuser
This diffuser was designed to snugly fit a canon 580EX flash not the Sigma 530. Attaching the diffuser takes a bit of effort so is removing. The vendor should advertise this product as a universal fit made for Canon flashes instead of advertising it specifically for the Sigma 530 flash only. I was tempted to return the product if not for the shipping which costs more than the item itself.

Doesn't fit perfectly but works fine.
The diffuser isn't an exact fit. You have to kind of push it on hard. It's snug and stays on. Works fine as a diffuser.
