Product Highlights
  • Lightweight, Collapsible Ring Light
  • Attaches to Lens, Fits Over Body & Flash
  • Provides Diffused, Balanced Lighting
  • Needs No Additional Power Supply

  • Easy Magnetic Extension Set-Up
  • Mirrored Interiors
  • Fits Most DSLRs and Flash Units
  • Designed for Standard & Telephoto Lenses
  • Includes Carry Pouch with Draw String

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" (10cm). 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.
Diameter 17.7" (45 cm)
Internal Dimensions 4.3" (11 cm)
Weight 11 oz (299 g)
Size When Folded 6.3 x 7.9" (16 x 20 cm)

      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.

      I have used this roundflash for several shoots mostly outdoors and a few indoors.
      The results are quite good. I like the lighting I'm getting from it.
      There are a few issues I found but of course there's never a perfect modifier.
      First, I'm using a 24-70 flash, and I can't shoot fully wide because the edges of the donut show up in the picture. I've had a number of shots with the black shade showing in the corners. I have to remember to zoom in to about 35mm or so and just step back.
      Second, occasionally it can get jostled and off-center and I go to take a picture and can't see anything until I re-adjust it.
      Third, when I'm shooting the model can't hear what I'm saying very well..your voice is muffled by the large round thing in front of your mouth.
      Fourth, and this is the one I'm most unhappy with..it seems to suck up flash power like mad on my 600EX. Either that or its overheating too fast...changing batteries gets it going again. But I need to experiment more to see if its just the overheating or the batteries really are low.

      Comments about RoundFlash Magnetic Ringflash Adapter:

      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.

      I've used this mostly for portrait shots in a more candid setting when you don't have regular studio lighting available. It gives a very nice soft even light. The only annoying feature is the white ring that appears in the subject's eyes, but this is easy to remove in Photoshop if you don't like it.

        I bought this ringflash adapter after a recommendation from a fellow amateur photographer at the NY Botanical Gardens annual orchid show. He showed me shots he was getting using it there and I've been using it since and loving the results. So far I haven't gone anywhere overly exciting, but when I get new camera toys almost everything becomes exciting to me. Looking forward to more fun!

          Compact and very efficient for the price. Don't forget to change the ETTL at 80 or 85 mm. Manual mode, 165, ISO 100, F8.0 and bang you have a nice shot in a few minute.

                I have this hooked up to my Canon 600EX-RT flash. It's compact and unfolds quickly. It's definitely bulky once unfolded. I keep flash exposure compensation to +1.5 to make sure it's bright enough, and I have to stay close to the subject.
                All that said, it gives you great images when used properly. You get that beautiful catchlight in the eyes, and it can rival a dedicated ring flash.
                The white surface is getting wrinkled with use, but so far it doesn't appear to effect the even distribution of light.

                      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 1~1.5 stops for flash compensation to make the ETTL work!

                                    it work great for only the head area, other than that it will appear under exposed, very portable and well built , though you will find the round flash hard to keep it straight and balanced with the lens. sometime i found the light reflection in the eyes is too much, still it will give very glamor touch if you only get very close to your subject .

                                      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.

                                      This is an inexpensive but effective entry into the ringlight world, useful for portraits or macro photogrphay. It providies very even light when attached to a quality speedlight, although it gets in the way of the focus ring (and aperture ring if you use one of those), so you need to set manual focus beforehand or use auto focus in the manner that you like to use it best. It is easily portable and easy to use.

                                        I am delighted to have the RoundFlash. I ordered it for it's ringflash quality but have also been using it as a off camera softbox. The ability to fold it down into a small bag makes for a lightweight easily transported modifier that is very easy to assemble. There is a downside in that it takes a few exposures to dial it in. Also it is difficult to use with zoom lenses as the zoom ring is hard to access when the system is fully assembled. I recommend using fixed lenses with autofocus. The focus ring is also difficult to access when fully assembled. Although it is not without it's problems, once dialed produces a nice image.I have also used this as a macro flash and found it helpful to use my left hand to focus in front of the RoundFlash. I find this much more efficient than focusing via the back of the RoundFlash...

                                          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.
