Canon EOS Auto Extension Tube Set

The Canon EOS Auto Extension Tube Set consists of three different sized extension tubes that fit a Canon EOS camera and enable the lens to focus closer than its normal set-minimum focusing distance.


  • Fits between the camera and lens to give a greater magnification
  • This set allows for up to seven different extensions
  • Designed with the correct mechanical coupling to maintain auto exposure

These Auto Extension Tubes are mounted between the Canon EOS camera body and the camera lens.

This set is supplied with three different sizes, 12mm, 20mm and 36mm, that give a total of up to seven different extensions. The longer the extension, the greater the magnification.

The Canon EOS Auto Extension tube is designed with all the circuitry and mechanical coupling to maintain the camera's TTL auto exposure.

It is recommend that you shoot with your lens in Manual focuses mode when using the Auto Extension Tubes to achieve clearer and much better results. Please note that auto focus may not be available depending on the amount of light entering the camera at the time.

This extension tube is aluminium constructed, protected with front and rear caps and compatible with Canon EF & Canon EF-S set ups.
