Abstract
A telescopic sight for a hand-held weapon comprises a housing for an optical system that presents a telescopic image to a user, and a zoom adjustment ring on the housing. The optical system has objective and ocular lens systems and between these an image erector lens system, and a sighting element bearing a graphic image pattern at either a first focal plane between the image erector lens system and the objective lens system or a second focal plane between the image erector lens system and the ocular lens system. An optical zoom system is linked to the zoom adjustment ring for effecting a change in magnification. The zoom adjustment ring is movable over the housing in opposite forward and rearward axial directions between a locked position and an unlocked position to adjust the zoom magnification. In the locked position interengaging formations between the ring and housing slides into engagement.
