Kenko Auto Extension Tube Set DG for Canon EOS Lenses

The Kenko Auto Extension Tube Set DG for Canon EOS Lenses comprises three tubes of varying lengths—12mm, 20mm, and 36mm—that can be utilized individually or in any combination to achieve the desired level of magnification. These tubes are compatible with both Canon EF and EFS lenses.

Extension tubes are specifically designed to allow a lens to focus at distances closer than its standard minimum focusing distance. This results in the magnification of the subject, making them particularly advantageous for macro photography, as they enable the transformation of nearly any lens into a macro lens while preserving its original optical integrity.

These extension tubes do not contain any optical elements. They are positioned between the camera body and the lens, increasing the distance between the lens and the film or sensor plane. By extending the lens away from the film or sensor, the lens is compelled to focus much closer than it typically would. The length of the extension tube directly influences how close the lens can focus.

The Kenko Auto Extension Tubes maintain autofocus functionality with Canon AF lenses, provided that the effective aperture remains at f/5.6 or brighter.
