WebSep 13, 2024 · The focal length of a lens determines its angle of view or field of view, and thus how much the subject will be magnified or reduced for a given photographic position. Short Focal Lengths. A shorter focal length results in a wider field of view. A short focal length. Image via Dave Bode Long Focal Lengths WebFor example, consider a normal lens for a 35 mm camera with a focal length of f = 50 mm. To focus a distant object ( s1 ≈ ∞), the rear principal plane of the lens must be located a distance s2 = 50 mm from the film plane, so that it is at location of the image plane.
