A camera with '''fixed focusing''' has no focus control. The focus is preset once and for all, at a distance for which sharpness will be correct enough for most subjects, usually from 1 meter (3 feet) to the infinity (far away). These cameras have a lens with a very small aperture (f/5.6 or f/8 for example). If they had a larger aperture they could not be sharp for both medium and long distance. | A camera with '''fixed focusing''' has no focus control.
