A binocular focusing mechanism for a binocular having a pair of telescopes disposed in parallel relation. The binocular has optical elements in each of the telescopes for magnifying an object image. The optical elements are focused by movement generated by the focusing mechanism which includes a pivotable knob operatively joined ot the optical elements. The knob is a generally elongated member normally extending generally parallel to the telescopes and is mounted between the telescopes in a plane extending generally parallel to the plane defined by the telescopes for pivotable movement about a pivot point located generally at one end thereof. The pivot point of the elongated member is defined by a fastener disposed generally perpendicular to the plane defined by the telescopes. The binocular also includes a finger contacting portion on the elongated member generally at the end opposite the pivot point of the knob. With this construction, pivotable movement of the elongated member about the pivot point causes movement of the optical elements to effect focus of the binocular.
