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 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.

Would this work on short lenses? I mostly use a 50mm prime lens for portraits
Asked by: Paige K.
I assume from the focal length that your portraits are taken with sub frame 35mm. I have only tested (and that was preliminary) with Pentax medium format, where some lenses are just too big for easy use with this device. For portraits, I would just mount it on its own stand. For Macro, on the other hand, one likely wants it centered. In that case the answer is likely lens specific.

Does this work with short lenses? Like a 50mm?
Asked by: Paige K.
This can work with a 50mm lens. With smaller lenses, a lens hood or a step-up ring can be helpful in keeping RoundFlash in place. Not all 50mm lenses are the same length, if you have a longer one you should be fine with just the lens itself.

question

Will this RoundFlash work with a Profoto B2 head mounted on camera with a ProMediaGear Boomerang flash bracket? If you remove the light stand bracket on the B2 head and mount directly to the Boomerang the distance from the head to the lens axis is pretty close to a large speed light.
Asked by: John H.
If you measure the distance from the lens' axis on your camera to the top of the flash when mounted on your flash bracket and it is between 5.3 (13cm) and 8.3 (21cm), then it may be compatible for use with the RoundFlash Magnetic Ringflash Adapter. However, I recommend measuring your equipment to check, as I think the height and the design of the bracket will have the flash sitting too high up above the lens for compatibility, and the size of the flash head (which is round and larger than a standard hot shoe flash head) may be too large to fit into the opening on the rear of the RoundFlash Magnetic Ringflash Adapter.

Do I need a tripod for this?

Not at all very portable a bit cumbersome at first but after a while you get used to it

question

How is this preferable to the RoundFlash dish? Is it that it's straight on from the lens? If the lens is what anchors it, then can I assume it wouldn't work off camera on a light stand?
Asked by: Joseph B.
The round flash support is dependent on the lens to be effective. I can imagine it being used on a flash propped on a stand, however, setup may prove difficult.

question

Hello. Could you please take a picture of your camera itself with this ring flash modifier on through a mirror? Expose it for the the ring flash, so that the flash itself is middle gray and everything else is black (it's going to be f/16 at ISO 100 or something). I wonder how even the light coming from the ring flash is. If you could post that picture here, I would really appreciate it.
Asked by: Till U.
If you search on the web there are numerous reviews and photos of the Roundflash in action. The light is quite even, due to the reflector design inside the modifier.
