Opteka Flash Diffuser for the Sigma EF 500 and EF 530 DG ST and Super Flashes

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.

User Ratings and Reviews

2 Stars 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.

4 Stars 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.

4 Stars 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.

4 Stars Opteka Flash Difusser
When I ordered the Opteka Flash Diffuser for the Sigma EF-500 & EF-530 DG ST & Super Flashes for my Sigma 530 ST, I was looking for something to help even out the light from this very powerful flash. I will admit that when it arrived I was concerned as the packaging was marked as a diffuser for a Canon 580 EX flash.

The Diffuser fit my 530 ST just fine though and works well for what it costs. Most of the time I use flash for real estate photography and this diffuser does a good job of spreading the light out evenly around the room. I would recommend it to owners of the Sigma 530 ST or Super looking for a cheap solution to diffusing your flash.
