Extension Tubes

Extension tube is a non-optical component used in macro photography, that mount between your lens and camera body and enable closer focusing. Its sole purpose is to move the lens farther from the image plane. The farther away the lens is, the closer the focus, the greater the magnification. By placing more space between your lens and the camera’s film plane or sensor, you are able to focus more closely on subjects and can bring the magnification ratio of any lens to 1:1 true macro and beyond.
