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.

RoundFlash Magnetic Ringflash Reviews

Nicely Even Lighting

By Moat

Folds up small, making it easy to place in a bag. Sturdy once unfolded. A bit tough to hold and balance with a camera and flash. Taller flash units fit better. Unique light makes an ideal travel ready Ringlight. Highly recommended. I would give five stars if the flash fit was a little better.

I really like this product, but it has just won negative feedback. My speed light overheated and stopped working. It seems that he just gets too hot with in the housing of the light. A dead skin of a nice even tone to the subject. Very light weight, but difficult to get back into the bag. Yes, I would deathly recommend this.

Great Results!!!

Great product. I have used this on a 430ex II, a 430ex III-RT and a 600ex-RT and they all fit fine. The diffuser spreads the light evenly and gives an interesting look along with that desired ringlight eye reflections. Setup is very simple and it folds small into the included bag. I would definitely recommend this product for photographers of all stages.

Great modifier to add to your toolkit

By Carl

This is an excellent modifier, and I find myself grabbing it more and more often for everyday shooting. While it is bulky, it weighs next to nothing. There is a Velcro strap to secure the flash to the device, but have found that it is not necessary to use this. Because of the light weight nature of the device, it is solid enough just strapped to the lens. I am using this with a Canon 430 EX iii RT on a 70D body. Falloff is pretty abrupt, so I find that I have to be conscious of the distance to subject and adjust FEC in ETTL mode a lot. However, in exchange for reduced bulk flash power, you get wonderful soft light without shadows. In my case, adjusting zoom on the 18-55mm kit lens or my 17-55 f2.8 is not much of an issue. The center is large enough that I can easily set it where I want. Obviously you would not want to be holding the lens when you take a shot, as that would block part of the light. I am sure that an actual ring flash would be a lot more convenient and using this has actually made me look more closely at them. However for occasional use or for a hobbyist learning on a budget, this is an excellent value. Others have commented that it was difficult to fold back into the small carrying bag. Personally I have not had any issue folding it as of yet.

It works as advertised. The materials and craftsmanship are quite nice. It diffuses the light well. Because of the design, the light does not spread much. So, it is better suited for close-up shots than distant ones.

Outstanding Design

I have traveled for a decade with the Alienbees ringflash for green screen photo composites. It works great but adds weight to my bags. With airlines getting tighter and tighter on rules and fees even for media I have been working hard to get my baggage weight down. This worked flawlessly with my speed lights. I am not so sure about using it handheld but on a stand it is excellent and the quality of the light is great even and shadow less.

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
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.

question

I don't understand how this product works. What is the light source of the ring? Does it just reflect ambient light like any piece of white paper would if placed in a similar position on/near the camera? If so, what is the advantage of the product compared with an ordinary sheet of paper? If the product has an internal light source, how is it powered (e.g., from the camera battery)?How is the product attached to the camera lens? Like a threaded lens filter? Is there electrical or mechanical connections with the camera body?Why is it described as magnetic?
Asked by: Anonymous
Essentially this item is just a large flash diffuser. 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 device uses your cameras hot shoe mounted flash as its light source. (If click on the main image of this item on this product link, you can then see other images which feature how the ring attaches and relates to the camera and flash etc). It is described as magnetic as the connection points on the frame are magnetic and allow for quick set up and break down.

question

If I'm shooting macro with the camera pointed straight down... vertical... will the ring still keep it's shape? So, for shooting an item... coin, etc.... that needs to be laid flat upon a tabletop background surface and shot at the perpendicular, will the unit work? Thanks B&H!Rex

Yes, the Roundflash Magnetic Ringflash Adapter will remain as a ring-shaped light diffusion if pointed vertically downward.

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.

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.
