The Kenko Auto Extension Tube Set DG consists of a 10mm and 16mm extension tubes that can be used individually or together. The Kenko extension tubes have all the contacts and circuitry to maintain communication between the camera body and the lens. AF (within the limited macro range) and auto exposure are maintained with these extension tubes.
Extension tubes are 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 DG 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 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.
Note!1. When using extension tubes the lens will not focus to infinity. The focus range will be greatly limited to a very close focusing distance.2. There is light fall off when using any extension tube, sometimes the equivalent of 3 f-stops of light is lost when using multiple extension tubes together. This light lost can affect the camera's ability to auto focus. Manual focusing is recommended should the lens begin to "hunt" (not lock onto the subject).
