ABSTRACT:
A binocular having a treadle-like knob which is coupled to optical elements to effect an adjustment such as focusing or varying the magnification of the optical system. The knob is mounted to be moveable in seesaw fashion about an axis which is generally perpendicular to the optical axes of the telescopes which form the binocular. This arrangement is especially useful in relatively small binoculars which may be held in one hand, the knob being driven by the tips of two fingers on the supporting hand.
