The Canon EF12II Extension Tube is used to allow a lens to focus closer than it would normally. This is accomplished by moving the lens 12mm farther away from the camera body's film plane or digital sensor by fitting between the camera body and the lens. Extension tubes are often used in macro photography or to help increase subject size in close up photography. Compatible with all Canon lenses, except the Canon 15mm f/2.8 fisheye, 14mm f/2.8L and MP-E 65mm f/2.8.
