The Dorr Extension Tubes 12/20/36mm for a Canon EOS fit have been designed to enable a lens to focus closer than its default set minimum focusing distance. When you focus closer, it has the effect of magnifying your subject, which makes it appear larger not only through your viewfinder but also in your pictures. The Dorr extension tubes are exceptional for macro photography, which enables you to convert almost any lens into a macro lens at a fraction of the cost. The Dorr extension tube is mounted in between the camera body & lens to create more distance between the lens & film plane. By doing this 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 Dorr Extension tubes set contains three tubes of different length, 13mm, 20mm & 36mm. These can be used individually or in any combination to obtain the desired magnification. ...
