The Kenko Extension Tube Set for Micro Four Third lenses is a set of two extension tubes designed to work with the mirrorless interchangeable lens cameras and are exceptionally useful for macro photography. The extension tubes mount between the camera body and the lens to create more distance between the lens and sensor. 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 Kenko Extension Set contains two tubes of different length, a 10mm and 16mm, which can be used individually or in any combination to obtain the desired magnification.
