Interchangeable-Lens Compact System Camera
Model Name35mm-Equivalent Focal LengthImage sensor size
EOS M2Approximately equivalent to 1.6 x the lens focal lengthAPS-C size
EOS MApproximately equivalent to 1.6 x the lens focal lengthAPS-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 Size35mm-equivalent Focal Length of Mounted LensExample:
Focal length image when using 50mm lens
APS-HEquivalent to "Lens Focal Length x Approx. 1.3"Equivalent to approx. 65mm when converted to 35mm
APS-CEquivalent 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)
