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 Name | Compatible |
| 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.
