Focal length vs magnification
WebFeb 16, 2014 · Magnification is the ratio between the subject's real size compared to it's projected size on the film/sensor. A 10mm object that appears 5mm across on the film/sensor will have a 1:2 magnification ratio. If it is projected at 20mm on the film/sensor, it will have a 2:1 mag ratio.
