Abstract
Auto-focus binoculars in which only the center portion of the image viewed through the ocular lenses of the binoculars is used for focusing. Light admitting windows are formed adjacent right and left objective lenses of the binoculars. Light from the light admitting windows is reflected by fixed and movable reflex members through long focal length lenses onto a focus detecting module. The movable one of the reflex members is reciprocated by a motor until an output signal from the focus detecting module indicates that focusing has been achieved.
