The electronic marco extension tube 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 (making it appear larger in the viewfinder and in your pictures). 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. The extension tubes have no optics. They are mounted in between the camera body and lens to create more distance between the lens and film plane. By moving the lens father away from the film or CCD 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. The set contains three tube rings of 13mm, 20mm, 36mm. Each part can be used separately or connected together for special need. What is more, 20mm & 36mm tube rings are designed with 1/4' tripod mount. Via the mount, it can be attached onto tripod easily and quickly, will save much and bring convenience. Compatible with all EOS EF / EFS lens and camera with EF/EF-S mount
