This Camera Field of View Calculator Provides the Lens Field of View from A Lens EFL and A Camera Sensor.
Camera Field of View Calculator
This calculator provides the camera's field of view based on an image sensor and a lens. 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.
The field of view is dependent upon the focal length of the lens, the image sensor size, the lens distortion, and the lens image circle. The calculator utilizes an advanced distortion model to calculate the FoV of wide angle and fisheye lenses. This distortion model covers most lenses, however, some lenses have a distortion profile that deviates from the model.
We help with calculations as part of our M12 lens and CS lens selection process and optical design services. Please contact us at firstname.lastname@example.org for more. A few examples are:
