WebApr 4, 2007 · To calculate the FOV from a focal length you also need the projected area size ie. “frame size” you are using. FOV (rectilinear) = 2 * arctan (frame size/ (focal length * 2)) Here “frame size” refers to the dimension of the frame in the direction of the FOV, so for 35mm (which is 24mm x 36mm), frame size is 36mm for the horizontal FOV ...
