Ring Light Filter Thread Adapters allow our LED ring lights and universal fiber optic ring light to connect directly to an imaging lens. The adapter slides into a flange protruding from the back of the ring light. Select the ring light adapter with the threading that matches the front filter threading of the lens. All feature an anodized aluminum construction.
Note: Though Ring Light Filter Thread Adapters can work with a wide range of imaging lenses, the working distance and field coverage provided by the LED ring light must be considered. Vignetting may occur on very wide angle imaging lenses.
