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.
