What is Focal Length? (And Why it Matters in …
WebFor example, a typical zoom lens might have a focal length of 18-55mm, or 24-70mm. Focal length comes from the distance between a specific part of a lens (the “optical centre”) and the image sensor (or film plane) where the image is recorded. The wider the angle of view that a lens offers, the smaller this distance, and the lower the number. WebFor example, an objective with a true focal length of 32 mm may then be said to have an effective focal length of 50 mm and thus function as a standard objective, rather than e.g. a macro or tele objective. It can be … shanfeng online store
