It is LA-55FZ220 - basically LA-55. Amazon has them. It is not a step ring. It is 55mm (I believe) and actually screws on to the camera where the lens hood normally goes. This way the TC lens weight is supported by it and the camera and not your zoom lens. I didn't understand it at first. IT's a little over 2 1/2 inches long. That TC lens is big and heavy so it's nice it doesn't hang off your lens, especially when zoomed out.
medavis43---Thanks. Problem solved.
