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

Optical elementsmeaning

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.

Optical elementslist

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.
