The Doctors Eyes Universal Adapter for SLR "Do-It-Yourself-Kit" facilitates attachment of the Professional Power & Light Controller (PLC-4) Ring Light System to any SLR camera that has a 1/4" tripod threading and no lens connectivity features. It starts with an adapter plate that connects to the PLC-4. A threading ring attaches to the adapter plate and then a magnetic coupling is attached to the threading ring. Finally, the PLC-4 attaches to your SLR camera's tripod attachment and the Ring Light is ready to be connected and held in place by the magnetic coupling.
