Telephoto ring set (10 and 16 mm) for Micro Four Thirds (m4/3) cameras

The Kenko zoom set includes 10mm and 16mm zoom rings, all of which transmit electrical signals, meaning aperture and focus information is transmitted between the lens and the body.
The zoom ring is placed between the camera body and the lens, which reduces the focusing distance of the lens. The more zoom rings there are between the body and the lens, i.e. the further the lens is from the body, the closer the camera can focus. With zoom rings, the lens cannot focus far away, so the rings are useful for close-up/macro photography. Zooming out reduces the lens's light output.
