FOTGA Macro Autofocus Extension Tube DG Adapter Ring for Micro Four Thirds Macro Cameras FOTGA Macro Autofocus Extension Tube DG Adapter Ring for Micro Four Thirds Macro Cameras FOTGA Macro Autofocus Extension Tube DG For Micro Four Thirds Macro Cameras Introduction: This high-quality auto macro extension tube kit is designed to allow lenses to focus closer than their normally set minimum focusing distance. Closer distances magnify the subject (making it appear larger in the viewfinder and in the photograph). They are extremely useful for macro photography, allowing you to convert almost any lens into a macro lens at a very low cost while maintaining the original optical quality. DG extension tubes do not contain any optical components. They are mounted between the camera body and the lens to increase the distance between the lens and the film plane. By moving the lens hood away from the film or CCD sensor in the camera, the lens is forced to focus closer than normal. The longer the extension tube, the closer the lens can focus. This product is supplied as a kit (10mm + 16mm). The kit includes two extension tubes of different lengths (10mm/16mm), which can be used in any combination or individually to achieve different magnifications. It features an electronic contact design, supporting autofocus, auto exposure, and other functions. You can use all shooting modes on your camera, but exposure compensation is required.
