Kenko AF DG Extension Tube Set (Canon EF)

Kenko EF-S AF DG Extension Tube Set (Canon)

The Kenko zoom range includes 12mm, 20mm and 36mm 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.

This zoom ring set works with Canon DSLR bodies and Canon EF and EF-S lenses.
