JJC AET-(II) series Automatic Extension Tube fits macro photography and allows your lens to focus closer than its normal minimum focus distance. By placing distance between your camera body and lens, focusing distance is shortened and the effect of magnifying your subject is created. Extension tubes are thus commonly used for macro photography and sometimes for closeup portraits. The extension tubes can be used individually or attached together to achieve your desired focusing result. These tubes are fully automatic tubes, so they are able to communicate all electronic functions from lens to camera including auto focus and auto exposure. The extension tubes have no optical elements so they will not degrade the quality of your lenses. A body cap and a rear lens cap are included in the package for better protecting your extension tubes when not in use.
