Canon EOS-M Auto Extension Tube Set

The Canon EOS-M Auto Extension Tube Set consists of three different sized extension tubes that fit a Canon EOS-M camera.

An extension tube is a spacer that sits between your lens and the camera body to alter the MFD (Minimum focus distance). The MFD of a lens is a measurement of the closest point a subject can be from the camera’s sensor, whilst still being able to focus. If a subject is closer to the sensor than a lens’ MFD, you cannot focus on that subject.

The more extension tubes used on a lens, the higher the lens magnification becomes as you’re able to move the lens much closer to the subject and still achieve focus. This means that any lens can be used to achieve macro-like photos.


  • 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-M camera body and the camera lens.

This set is supplied with three different sizes, 10mm, 16mm and 21mm, that give a total of up to seven different extensions. The longer the extension, the greater the magnification.

The Canon EOS-M 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 plastic constructed and is protected with front and rear caps.
