The 518AF Digital Ring Light is geared for Close-up Macro photography and is fully compatible with Digital & Film SLR Cameras. It is the easy to use solution for getting extra close without loosing your light supply while at the same time retaining even, uniform light at the correct color temperature. Perfect for Dentists and Optometrists
Attaching the 518AF to the front of the lens on your camera enables the illumination of your subject in Macro Close - Up photography at a shooting distance of up to approximately 2.5cm ( 1.0 in. ) - something your camera's built-in flash may not be able to do.
The 518AF is powered by a built-in lithium-polymer battery which can last up to 45 minutes for constant lighting when fully charged. (AC Power adapter is supplied for recharging.)
