Zeikos ZE HD580 Flash Diffuser Canon Review

There were no reviews for this product, so I bought it because of its price. I have never used a diffuser but I expected a very soft throw of light from this product; But this was not the case. There is some spread compared to direct flash, but it is not significant. This diffuser isn't creamy white plastic, it's more like a translucent plastic alcohol bottle - I don't know if that has an effect. I used it on a 580EX II and it was VERY tight.
