WebThis is because short focal lenses are more curved. In the thin lens approximation, the focal length of a lens of index n in air with radii of curvature R 1, R 2 is given by: 1 f = ( n − 1) ( 1 R 1 − 1 R 2) As a lens focal length gets longer and longer, the lens becomes less and less curved. An infinite focal length lens would be a pane of ... WebApr 4, 2024 · This is exactly the same as a 0.5X maximum magnification or 50% magnification. The three ways of expressing magnification tell us the same thing. 1:2 = 1/2 = 0.5 = 50%. If the lens can focus closely enough to project a life sized image onto the sensor, it has 1:1 / 1.0X / 100% magnification.
