Solution
The lens focal length in terms of the EF lens' 35mm-equivalent focal length is as follows.
| Model Name | 35mm-Equivalent Focal Length | Image sensor size |
| EOS M3 | Approximately equivalent to 1.6 x the lens focal length | APS-C size |
| EOS M5 | Approximately equivalent to 1.6 x the lens focal length | APS-C size |
| EOS M10 | Approximately equivalent to 1.6 x the lens focal length | APS-C size |
| EOS M2 | Approximately equivalent to 1.6 x the lens focal length | APS-C size |
| EOS M | Approximately equivalent to 1.6 x the lens focal length | APS-C size |
The shooting screens of the APS-H size camera and APS-C size camera have smaller designs than the shooting screen of the 35mm half-frame camera.
For this reason, the 35mm-equivalent focal length and the focal length image of the mounted lens are as follows:
| Image Sensor Size | 35mm-equivalent Focal Length of Mounted Lens | Example:Focal length image when using 50mm lens |
| APS-C | Equivalent to "Lens Focal Length x Approx. 1.6" | Equivalent to approx. 80mm when converted to 35mm |
- APS-C size
A 50mm lens is approx. equivalent to an 80mm lens (when the angle of view is approx. 1.6 x)
