A lens that is preset to a given focus distance, it has no autofocus mechanism, set to give the camera the maximum depth of field.
Refers to a lens, the focus of which cannot be changed. Found in simple cameras, the focus is preset (or fixed) by the factory, usually at the hyperfocal distance, resulting in image sharpness for most common shooting conditions for snapshots.
The camera's focus is pre-set to a distance at which most subjects or objects will be in focus from near to far. Not as precise as Auto-focus.
A lens system that doesn't require focusing. Most point-and-shoot automatic cameras have a fixed-focus lens.
Lens camera system that has no method of focusing on a fixed point, usually at the hyperfocal distance.
An optical instrument lacking the ability to change focus.
A camera with fixed focus has no focus control. The focus is preset once and for all, at a distance for which the depth of field will suffice for most subjects. With a slowish and moderately wide lens for a frame (negative, slide, or CCD) of 24×36mm or below, the depth of field may go from one meter to infinity.
