Fixed focus refers to a type of lens that cannot adjust its focal point, the distance where images appear sharp and in focus. Fixed focus lenses rely on their typically large depth-of-field in order to ensure that most commonly photographed subjects are reasonably in focus. A fixed focus lens will sometimes be designed to have a bias toward either portrait or landscape/scenery photographs.
