What Is an EF-M Lens? (Interchangeable-lens Digital Cameras)

25-Sep-2019

Solution

    An EF-M lens is a lens for an EF-M lens-compatible interchangeable-lens digital camera.

    Using an EF-M lens-compatible interchangeable-lens digital camera with an APS-C-size image sensor, the replacement lens's 35 mm equivalent focal length is approximately 1.6 times greater, and the angle of view is more like that of a telephoto lens as a result. For example, if a 50 mm lens is attached to a camera with an APS-C-size image sensor, the 35 mm equivalent focal length will be approximately 80 mm.



    Only the following cameras are compatible with EF-M lenses.
    Model NameCompatible
    EOS M
    EOS M2
    EOS M3
    EOS M5
    EOS M6
    EOS M6 Mark II
    EOS M10
    EOS M100
    EOS M200
    EOS Kiss M

    When attaching the lens to the camera body, align the round, white mount index.
