The pitch of a camera's lens mount is the?

The pitch of a camera's lens mount refers specifically to the distance between the rear mount of the lens and the image sensor. This measurement is critical because it defines how far the lens is positioned from the sensor, which affects focus and the overall optical performance of the camera. If this distance is not correctly specified, it can lead to issues such as poor focus or vignetting, where the corners of the image may appear darker than the center. Understanding this concept is fundamental for proper camera setup and achieving optimal image quality in closed circuit television (CCTV) systems.
