WebOct 2, 2015 · The focal length is a measurement taken when the camera is focused on a far distant object. By distant we are talking about a star. Opticians often make an artificial star target which is simply an illuminated pinhole. A far distant subject is said to be at an infinite distance (symbol ∞). Web1 Answer Sorted by: 3 The field of view can be shown to be θ = 2 tan − 1 D 2 f where D is the dimension of the sensor (width or height) and f is the focal length. You can derive this easily using similar triangles as in the figure below, where ϕ is the half field of view.
