Extension tubes are thus commonly used for macro photography and sometimes for close up portraits.JJC Automatic Extension Tubes are available as a set (12mm,20mm and 36mm), or as individual tubes in 12mm, 25mm to fit Canon EOS.They can be used individually or together to create the desired magnification effect. 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. Extension tubes have no optical elements so they will not degrade the quality of your lenses.
