The Orbis Ring Flash is designed to affix onto the front of a common shoe-mount flash and is suspended around the circumference of a lens. The Orbis does not produce light independently, rather it is a light modification device that produces an effect similar to studio ring flashes usually costing ten times the price of the Orbis.
A ring flash is one of the best ways to light for a still-life, portrait, or macro shoot. Its effect is unmistakable and very distinct.
As a flash attachment, the Orbis requires a shoe mount flash and a PC cord, off-camera cord, or wireless flash trigger.
Lens port diameter is 86mm so most SLR lenses are compatible. Orbis must be hand-held.
Designed for portability, the Orbis packs neatly into a camera bag and is a fraction of the bulk and weight of a traditional studio ring flash and power supply.
As of this writing, the Orbis Ring Flash has been tested with the following: Canon 300TL, 420EX, 430EX, 540EZ, 550EX, 580EX I and II, Nikon SB28, SB600, SB800, SB900, Cosmos 360, Vivitar 283, Olympus FL36R, FL50, Sunpak PF30X and 5000, Sony F56, Minolta 5200 and Sigma 500, Metz 48 and Metz 58 and Pentax AF540.
