Field of view calculator

Calculate the field of view and angle of view at any focal length and (almost any) distance.

Please note that due to the capricious nature of lenses at macro distances that these values will only be accurate when the subject distance is considerably greater than the focal length. Additionally, these results only apply to rectilinear lenses (the fisheye ZD8mm lens has a diagonal angle of view of 180°)

If you know your desired field of view and want to know what focal length/distance combinations work, you'll like our reverse field of view calculator.
