18 Σεπ 2023 · The exact definition is: Focal length measures the distance, in millimeters, between the “nodal point” of the lens and the camera’s sensor. “Nodal point” may sound complicated, but it is simply the point where light converges in a lens.
13 Μαΐ 2023 · Many new DSLRs and mirrorless cameras are usually sold with a lens that typically offers a range of focal lengths between 18mm and 55mm - offering a choice of angles of view from moderate wide-angle to short telephoto, with these camera's APS-C-sized sensor.
11 Ιουλ 2019 · This post explains camera lens focal length for filmmaking, and how you can use different lens magnifications to create stunning visuals for your projects.
Camera lens focal lengths are usually specified in millimetres (mm), but some older lenses are marked in centimetres (cm) or inches. Focal length ( f ) and field of view (FOV) of a lens are inversely proportional.
Focal length is the system used in photography to describe how wide or tight a lens is. Listed as a number and measured in millimetres — e.g., 35mm, 85mm — it tells you how much of a scene a lens can capture, and how big subjects will appear. The number gives an indication of the angle of view that a lens can see.

The focal length of a lens is determined when the lens is focused at infinity. Lens focal length tells us the angle of view —how much of the scene will be captured—and the magnification —how large individual elements will be.
