What is the formula of FOV?
Focal length (f) and field of view (FOV) of a lens are inversely proportional. For a standard rectilinear lens, FOV = 2 arctan x/2f, where x is the diagonal of the film.
Which part of the camera indicates the field of view?
In photography and filmmaking, the FOV refers to what is visible through the camera lens or optical viewfinder. Changing the lens changes the FOV. To increase FOV and capture more of a scene, a wide-angle lens -- which displays a wider field of view than our human vision -- is used.
Is angle of view the same as field of view?
Field of view (FOV) refers to the actual dimensions of the full frame. This is typically measured as a length on the horizontal plane of the frame. Angle of view refers to the angle that the lens allows in light, which dictates the field of view.
