ABSTRACT:
A binocular is provided with a pair of telescopic optical systems. Each of the pair of telescopic optical systems has an objective lens, a pair of positive and negative compensation lenses, an erecting system, and an observing optical system. The negative compensation lens of the right telescopic optical system and the positive compensation lens of the left telescopic optical system are held by a rotatable first frame. The positive compensation lens of the right telescopic optical system and the negative compensation lens of the left telescopic optical system are held by a rotatable second frame. The first and second frames are driven in the opposite directions to each other such that the vibration of the image can be compensated.
