JJC AET Series of Automatic Extension Tubes 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. Among JJC AET series of automatic extension tubes, AET-CS is a set including 12mm, 20mm, and 36mm automatic tubes, and so is AET-NS; AET-M43S is a set including 10mm,16mm automatic tubes and so is AET-NEXS; AET-C12 is a 12mm tube and AET-C25 is a 25mm tube.
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. Please note that JJC AET-FXS automatic extension tube compatible with Fujifilm X-mount is also coming soon.
