Calculate FOV from focal length

Calculate FOV from focal length

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.

  1. How do you find FOV?
  2. What is the FOV of a 50mm lens?

How do you find FOV?

Field of View = Field Number (FN) ÷ Objective Magnification

For objects that require higher magnifications, convert your measurements from millimeters to micrometers.

What is the FOV of a 50mm lens?

The FOV for a 50mm lens would be 39.6 degrees horizontally and 27.0 degrees vertically. Diagonally, the FOV is 46.8 degrees.
