This Kenko DG Extension Tube Set for Canon is designed to enable a lens to focus closer than its normal set minimum focusing distance. Getting closer has the effect of magnifying your subject. This set has tubes of 12mm, 20mm and 36mm. The tubes can be used with EF and EF-S (not EF-M) lenses individually or in combination to obtain the desired magnification.
They are exceptionally useful for macro photography, enabling you to convert almost any lens into a macro lens at a fraction of the cost while maintaining its original optical quality. These Kenko extension tubes are designed with all the circuitry and mechanical coupling to maintain auto focus and TTL auto exposure with Canon EF and EF-S lenses.
