Focal length scaling
WebLenses with longer focal lengths, such as 200 mm, give you narrower angles of view. The focal length of a lens is the optical distance (usually measured in mm) from the point where the light meets inside the lens to the camera’s sensor. “You can zoom in on your phone, but that’s not changing your focal length. WebFocal length, usually represented in millimeters (mm), is the basic description of a photographic lens. It is not a measurement of the actual length of a lens, but a calculation of an optical distance from the point …
