Wasn’t sure if it would fit smaller speedlights, but it fits and works just fine. Used first time for a wedding shoot and it made life much easier and ‘stress free’, with terrific results. I’m very impressed with its quality & resilience, as it ‘folded’ neatly into my camera bag and was super quick to whip it out and pop it straight on to my flash. It gives confidence in getting great results from on-camera flash photography, without thinking too much about bounce and flash settings. Other than one or two tweets to aperture and ISO, event flash is now a doddle!
