How to Attach or Remove a Lens from a Canon EOS 70D
  1. Turn the camera off and remove the cap that covers the lens mount on the front of the camera.
  2. Remove the cap that covers the back of the lens.
  3. Locate the proper lens mounting index on the camera body.
  4. Align the mounting index on the lens with the one on the camera.

In respect to this, how do I know if my Canon lens is compatible?

The easiest way to find out which lenses your camera will accept is to look at the indicators on lens mount on the front of your camera. Simply remove the lens from your camera by pressing the lens release button and twisting the lens anti-clockwise.

Beside above, how do I know what lenses are compatible with my camera? If you see a red circle on the lens mount your camera will accept EF lenses.

  • If you see a red circle and a white square it will accept EF-S lenses as well.
  • If you see a white circle it will accept only EF-M lenses.

Are Canon EF and EFS lenses interchangeable?
