Model Name | 35mm-Equivalent Focal Length | Image sensor 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-H | Equivalent to "Lens Focal Length x Approx. 1.3" | Equivalent to approx. 65mm when converted to 35mm |

APS-C | Equivalent to "Lens Focal Length x Approx. 1.6" | Equivalent to approx. 80mm when converted to 35mm |

- APS-H size

A 50mm lens is approx. equivalent to a 65mm lens (when the angle of view is approx. 1.3 x)

- APS-C size

A 50mm lens is approx. equivalent to an 80mm lens (when the angle of view is approx. 1.6 x)
