Asitis, a company based in Kraków, Poland, have released a new kind of speedlight ring flash adapter called the Roundflash. Unlike plastic ring converters, this solution is a bit different. The Roundflash is made of fabric and rods, collapsing much like a softbox.


At 44cm (17″) in diameter, the assembled Roundflash provides quite a large light source, especially when compared to alternative adapters. According to company tests, photographers can obtain exposures of f11.7, Iso 400 at a distance of 1 metre using a Canon Speedlite 580EX II at full power.

The central hole accepts lenses up to 10cm (4″) in diameter and tightens to them with bungee cords. At just 227g (8 oz) – half the weigh of the Orbis, RayFlash and O-Flash – you can mount the Roundflash to your camera and still hand-hold the setup with relative ease.

Roundflash in use

A selection of sample photographs using the modifier may be seen in the Roundflash group on Flickr.

  • fresko

    too expensive

  • Nice invention! Price is not to bad when you compare it with the Obis or Ray flash and you can put this ringflash adapter easy in your photobag.
    This is good for the backpackers strobist photographers.

  • Does anyone know if the light is diffused evenly? It seems like the light would be more intense at the top and disapate towards the bottom.

  • Interesting that most of the images in their Flickr gallery have been shot with a +1.5EV when coupled to a 580exII and eTTL
