Fotodiox Pro Canon EOS Auto Macro Extension Tube Set Kit for Extreme Close-Up with Autofocus and Auto-Exposure

A macro extension tube is a wonderful substitution for the expensive macro lens. The lens transforms into a macro lens while maintaining its optical quality. By placing distance between your camera body and lens, focusing distance is shortened and the effect of magnifying your subject is created. Fotodiox Pro Auto Macro Extension Tube Kit for Canon EOS is a set of automatic tubes that are able to communicate all electronic functions from the lens to camera including autofocus and auto-exposure. The kit contains three extension tubes of 13mm, 21mm, and 31mm in length. The extension tubes can be used independently or added together for extreme macro photography. No other optical components are added with this kit, so the image will preserve the original optical properties of the lens.
