How to Calculate Crop Factor

WebA fixed focal length lens, also known as a conventional or entocentric lens, is a lens with a fixed angular field of view (AFOV). By focusing the lens for different working distances (WDs), differently sized field of view (FOV) can be obtained, though the viewing angle is constant. AFOV is typically specified as the full angle (in degrees ... WebWhat is Lens Focal Length. Focal length, usually represented in millimeters (mm), is the basic description of a photographic lens.
