The Cobra Macroflash Automatic Ring Light is a convenient and creative lighting solution for medical, dental, flower, insect, jewelry, coin, and other small subject close-up photography where built-in and conventional flashes are impossible to use. The circular flash tube design encompasses your lens to provide shadow-free, even illumination on your subject. An added benefit of employing electronic flash technology rather than a continuous light source is that it will freeze action, so that a lively butterfly or flower waving in the breeze can be photographed as if they were posing for your camera. Unlike other ring lights that require a bulky and heavy power supply, the Macroflash is self-contained and powered by only two AA-size Alkaline, NiCad or NiMH rechargeable batteries. A PC cord and Hotshoe-to-PC adapter are supplied, enabling the Macroflash to be used with almost any Canon Digital or Film SLR Camera with a hotshoe or standard PC socket.

This versatile Ring Light Flash can mount to almost any Canon Digital or Film SLR lens using the supplied 52mm, 55mm, and 58mm adapter rings — or if necessary, with other optionally available adapter rings. Optimized to prevent vignetting with most lenses having a filter size of 58mm or smaller, these optional Series 7 adapter rings are available separately in sizes from 43mm through 77mm.

Provide your camera with plenty of power with 4 ultra-high capacity 2900mAh Nickel Metal Hydride (NiMH) batteries and a multi-voltage rapid charger.
