The Magnetic Ringflash Adapter from Roundflash is a portable, collapsible ring light that attaches to the lens of your DSLR with an external flash attached and provides a bright, evenly diffused light that is effective for portraits and for macro shooting. Due to its large diameter and internal mirrored construction, RoundFlash provides soft and flattering lighting without hotspots, heavy shadows or dark areas on the front surface. The diffuser works with your speedlight to provide the light output you desire. It is ideal for portrait work because of the diffused light it supplies but also works well for macro shooting due to its placement on the lens. 

The RoundFlash fits most DSLRs with external flash units and easily attaches to the lens via a set of pentagonal shaped stretch cords and fixes securely to the flash unit with a touch fastener. The diameter of its internal hole is 4.3", so it is compatible with any lens with a diameter smaller than 4.0" (10 cm). It is designed to work with standard length and telephoto lenses and can work with wide-angle lenses, however some vignetting may occur depending on the lens. The RoundFlash diffuser opens easily and is supported in its open position by five foldable magnetic sticks. It collapses and folds down to fit into an included 6.3 x 7.9" pouch.

Bright, Consistent Lighting
The large diameter allows you to light objects with a big, round, smooth ring light. The light from a powerful hot-shoe flash bounces off the mirrors and surfaces inside to create an evenly lit front panel.
No Additional Power Supply or Equipment
All you need is the gear you already have. Use your powerful speedlight as a ring flash without any cables, brackets, or even a power supply.
Lightweight and Portable
At just 11 oz (299 g) and without a power supply, the RoundFlash is lightweight and does not put strain on your flash or lens. It folds down to fit inside the included 6.3 x 7.9" carry pouch with draw string.
Magnetic Set-up System
The brand new patent pending magnetic set-up system enables you to set-up and break-down the RoundFlash in a few seconds.
Fits Most Flashes
The universal attachment holds the flash securely in the right position in both landscape and portrait orientations. RoundFlash fits all body+lens+flash combinations within the range of 5.3" (13cm) and 8.3" (21cm) measured from the lens' axis to the flash head opening.
Fits Most Lenses
A star-shaped stretchy rope ensures your RoundFlash is centered and allows you to adjust it if needed. Once it's mounted, it holds all lenses with the front diameter of up to 4" (100mm). It is designed to work best with standard length and telephoto lenses although can work with wide-angle lenses depending on their size. With smaller lenses, a lens hood or a step-up ring can be helpful in keeping RoundFlash in place, however some vignetting may occur with certain wide-angle lenses.

    Rated 5 out of 5 by from I hate to give away my secret. I bought this little gadget, thinking it might be a little better than on-camera pop-up flash when those rare times dictate such inappropriate behavior. But I have been very impressed. It is my 'go to' flash modifier when shooting on the fly in ever-changing conditions where I cannot set up lighting and cannothave a model stay in one place (photo 1, male). I also use it as fill flash, off-camera (photo 2, female). I have been very content with the results and now keep it in my kit at all times. Thismodifier willprovide soft, even lighton-camera and off-camera.

    Rated 5 out of 5 by from inexpensive ring flash simulator In my studio I use a very expensive ring flash on manual exposure along with my other studio lighting for different styles of portraits. Taking my studio ring flash outdoors for fill flash on backlit subjects would be cumbersome so I got this inexpensive ring flash simulator. If I put my on camera flash and camera on manual, I can use this simulator for fill flash outdoors on back or side lit subjects which opens up a whole new style of portrait photography

    Rated 4 out of 5 by from A little clumsy but worth it! I originally tried the beauty dish attachment but it fell in front of the camera. So far, I love this ring flash. It gives me an entirely new realm to learn and a completely different feel to my photos. It is a bit clumsy to use though because you have to stick your hand around in order to use the manual focus or push it off temporarily to focus. I guess you can stick with auto-focus but then it will delay some of your photos. It is also a bit silly when it folds up and doesn't completely fit in the bag. Overall, it's worth it if you are just running around and want a new look to your shoot. Works well in the dark as well

    Rated 4 out of 5 by from So Far, So Good I'm shooting a wedding for a friend coming up and wanted to do several different styles of portraits and thought this would be a great addition. My test shots have come out well and I expect to further tweak my technique in the next few weeks leading up to the wedding. I've been impressed with the quality of the device although it is a tad expensive for what it is. It can be a bit of a trick get on/off at times and as mentioned it will block your flash sensor so it helps to shoot at the very least in the amount low light that your camera can focus through just using the AF sensors through the lens. Using manual focus is not easy on a 24-105mm L with the round flash on. Overall its been exactly what I expected and needed. Happy with the purchase.

    Rated 4 out of 5 by from My choice over the standard Ring Flash! I picked this product over a ring flash because having done a bunch of research and looked at sample photos, this was a softer light with a more flattering catchlight. I would not recommend this as an event flash, it's very lightweight but is pretty big and looks intimidating. This light gave me the exact look I was going for, which was the look of a standard ring flash but with a more distinct and large round catchlight in the eyes of my subject. For that type of look, this is perfect. I'd call it a one trick pony, but that one trick is amazing! In order to get this look, you must shoot close to the subject, the farther you are away the smaller the catchlight will appear in the pupils. Some things I like it about it include the fact that it is very compact and lightweight. Comes with a nifty little bag to store it, and fits easily into a camera bag. I liked how quick it was to assemble, simply unfold, and connect the magnetic pins to lock in place. One thing I did not like is that not all lenses work well with this. You almost need to use a medium length or telephoto lens for it to fill the Roundflash. A short lens like a prime 50mm will not be secure. Bigger lenses fit nicely in the middle of the elastic bands.

    Rated 4 out of 5 by from Works as advertised Works as advertised. Somewhat of a hassle to get the lens into the bungees and after its on, to operate the lens zoom, but overall does what it says and produces a nice light. Would like to see it side by side with the orbis. Given the way the flash attaches to this, its not real useful to use it off camera, whereas I know a few people that use the orbis as an off camera light modifier by using Nikon CLS or attaching a trigger to the flash. Compact when folded up but bulky when in use. For my needs and for the price though, this is a solid selection.

    Rated 5 out of 5 by from One of the best Ringflash adapter! This is really one of the best ring flash adapters out there. First of all, its compact when compressed, nice to carry around. Easy to set up or collapse it to store. Second, it is very light weight! you really dont feel much additional weight to the camera. Now the quality of the light, it is just memorizing! the light is very evenly spread, you can barely notice that the top of the ring might be a bit weaker. The catch light it creates its just phenomenal! and the shadowless light is good for any macro shot. Keep in mind that you need to add 11.5 stops for flash compensation to make the ETTL work!

    Rated 4 out of 5 by from Stellar for autofocus This is my first ring-flash tool so I was a bit out -of-sorts while figuring it out. It's amazing so long as you're not using a manual focus lens...which is a shame, because it would be AMAZING on my 85mm. Light as a feather...cute as a button and all that. Takes some practice, but I consider it a strong buy. Knocks product photography onto next millennium. That barrier between photographer and subject gets real serious using this though,,,so get used to talking a bunch. No issues with my flash falling out like some have reported.
