Overview
The Auto Extension Tube Set DG for Canon EOS Lenses from Kenko contains three tubes of different lengths--12mm, 20mm, and 36mm-- which can be used individually or in any combination to obtain the desired magnification. They are compatible with Canon EF and EFS lenses. The extension tubes have no optics. They are mounted between the camera body and lens to create more distance between the lens and film/sensor plane. By moving the lens farther away from the film or sensor in the camera, the lens is forced to focus much closer than normal. The greater the length of the extension tube, the closer the lens can focus. Plus a General Brand Lens Cleaning Kit.
