http://kmp.pentaxians.eu/technology/fov/ WebThe calculator below converts between the focal length f and the field of view (FOV) of a rectilinear lens. The formula that it implements is FOV = 2 arctan (x / (2 f)), where x is the diagonal of the film. The FOV is measured across the frame’s diagonal, and is therefore smaller across the horizonal dimension, and even smaller across the ...

WebMar 10, 2024 · AFOV – Angular Field of View. HFOV – Width of the object seen through the lens. Working distance (WD) – Distance between the lens and the object. However, in most cases, the FOV of a lens is expressed using DFOV or Diagonal Field of View. So, you might have to calculate the DFOV value as well. Let us see how that is done. WebCamera lens focal lengths are usually specified in millimetres (mm), but some older lenses are marked in centimetres (cm) or inches. Focal length ( f) and field of view (FOV) of a lens are inversely proportional. For a standard rectilinear lens, FOV = 2 arctan x 2 f, where x is the width of the film. tally for construction
