This Camera Field Of View Calculator uses the Lens EFL, Distortion, and an Image Sensor.
Camera Field of View Calculator
This calculator provides the camera's field of view based on an image sensor and a lens. The field of view of a camera is dependent upon the focal length of the lens, the image sensor size, the lens distortion, and the lens image circle.
The calculator provides three values: horizontal field of view, vertical field of view, and diagonal field of view. The calculator also provides the equivalent EFL for a zero-distortion 35mm full frame type lens.
Additionally, it uses distortion to calculate the FoV of wide angle and fisheye lenses. It includes the Distortion (%) relative to F-Θ and Rectilinear projections. The equations used are a generalizable form of the fisheye lens distortion equations described on Wikipedias' Fisheye Lens page.
