Is there a formula for calculating the required focal length for a webcam given the width of the field of view and the distance away from the subject the camera is?(adsbygoogle = window.adsbygoogle || []).push({});

Also is there a relationship between the focal length of a webcam and the 'fish-eyedness' or distortion of the picture?
