The 21mm Pro Auto Macro Extension Tube from Fotodiox is suitable for use with Canon EOS EF & EF-S Lenses for extreme close-up. It is an automatic tube that is able to communicate all electronic functions from the lens to camera including autofocus and auto-exposure. No other optical components are added, so the image will preserve the original optical properties of the 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.

Any combination of tubes can be used for various reproduction ratios
No optical insert - maintains lens optical quality
Maintains the electronic functions of the lens, including auto-focus and auto-exposure

    Pro Auto Macro Extension Tube for Canon EF & EF-S Lenses (21mm) is rated 4.0 out of 5 by 4.
    Rated 5 out of 5 by from Fantastic Tool I can't say enough about how I loved the�FotodioX Pro Auto Macro Extension Tube for Canon EF & EF-S Lenses (21mm). It worked like a charm on all of my lenses.....some better then others. But in the end, I liked it best on my Canon 24-70, 2.8 lens.� It felt solid in my hands, and went on the camera, and lens with no trouble. All the camera functions worked. I would recommend the FotodioX Pro to anyone that asked for a recommendation. And plan on buying the other two later, so that I can stack them for even closer images.

    Rated 4 out of 5 by from Overall, a nice item! Worked as described. It was a little tight on my 6D. I was almost afraid I wasn't putting it on correctly, but then after twisting just a little bit harder than usual, it installed. It first it wouldn't communicate with the lens when I added it, so I took then lens back off and lightly cleaned the contacts with a cloth and it has worked perfectly ever since!

    Rated 5 out of 5 by from Finally decided to try it. Wasn't sure if I want to try an extension tube, but glad that I did. It gives me that extra little bump to get really close up. It attaches easy to my Canon T3 and all of my lenses, so far all of my pictures are sharp and in focus.

    Rated 2 out of 5 by from Does not work with my Canon EOS Rebel T-21 60 mm macro I got this to add to my EFS 60mm Canon Macro lens To starts fits a bit rough and would not focus any closer than my 60 mm
