Angle of view and field of view
with standard focal length lenses on full frame versus FOV cropping digital SLR cameras:

1.0 x : Full frame and film 24x36 format
1.5 x : APS-C
1.6 x : APS-C Canon
2.0 x : MFT

Note: Many digital cameras have sensors that are slightly smaller than the nominal dimension, i.e. 35.6 x 23.8 mm rather than 36 x 24 mm.

Note: The AoV and FoV listed below are for perfectly equiangular fisheye or perfectly rectilinear lenses. Most (all) lenses have mapping functions that differ slightly from the perfect theoretical projection, or even a slightly different focal length, thus the actual AoV and FoV will differ slightly from the ones listed in the table.
