Omni-Bounce OM-ET Flash Diffuser (for Canon 600EX-RT & Yongnuo YN600EX-RT)

The perfect no-nonsense modifier for the Canon Speedlite 600EX-RT. I have used Stofen omni-bounces for years on my various Speedlites.The omni-bounce very evenly spreads light and most commonly I use it when my flash is tilted to 45-90º, which results in more forward fill when bouncing up. This works well to provide a more natural looking light source (i.e. from above), but helps to prevent unpleasant shadows in the foreground. I haven't measured the light loss but have seen it estimated at ~1 stop, which is consistent with my experience. Fit is quite tight (tighter than my prior 580EX omni-bounces), but I think I prefer it. There's no give or feeling that these will drop off during use; however, as a result it takes a bit of a pull to remove. In my opinion this should be in any 600EX owner's kit.

These fit the Canon Flash perfectly and are light and easy to pack. It is meant to create a bare bulb effect with the flash - so rather than a directed flash, this sends flash in all directions like a light bulb. It works best when there are surfaces to bounce off of nearby - otherwise it simply reduces/wastes flash power. Any softening of light is from the bounce effect, not from the diffuser - hence the name "Omni-BOUNCE"! Bounce it. For the price, you can't beat it.

This diffuser is an excellent modifier, especially for the price point. It fits with no problems on my Canon 600 ex-rt. I had a home-made one, that served me well for my 430 EX II, but this snugger fit will keep it from falling off. The light diffuses nicely and makes using a flash on camera possible for those times when you can't get the flash off camera. My family has very deep-set eyes and bouncing does not work, so this is a life-saver for me.

Seems pretty good. Wish it diffused the light a little more, but definitely better than just the flash itself. Can’t beat it for easy, on camera applications. Fits fairly tight and won’t fit back in the 600ex bag with it on.

They're a little overpriced for what they are, but they work great. I finally got around to buying one because I needed it for an interior architecture job I had. I did a Guide Number test and determined that this drops the GN on the 600EX-RT by about 3 stops to 14 at max power. If you're in a room with walls and a ceiling then the decrease in stops will not be as severe and is probably the 1.5 stop decrease claimed on the literature. I did my test in a non-bouncing testing area. These are up there with the Gary Fong products. Gary Fong is a bit better but these have an advantage of being compact.

It does it's job at flash diffusion, but I struggle to put it on and off of the flash. It's a super snug fit to the point where I'm wrestling to get it off the flash using both hands. The edges seem a bit concave, so I have to pull out the bottom edge so that it will fit. I had a knock off brand for my 580EX ii and it worked perfectly, nice fit and easily came off with a firm pull.

This is a great diffuser that creates soft neutral-warm light. I have used it extensively in a wide variety of situations with excellent results. Works very well for fill flash, accent or key lighting. I would compare it in function to the gary fong cloud dome diffuser. The gary fong is slightly softer and a bit warmer, but is also much bulkier in the camera bag (the gary fong collapsible lightsphere is brighter and cooler than both the sto-fen and the cloud dome). If I am on the go I use the sto-fen. If I am stationary I use the fong.

This thing is great. It fits so tight that it will never fall off. My other one I had on a different flash fell off constantly. I’m surprised I never lost it. This one will never get lost
