Abstract

An anti-vibration optical system is an observation optical system including, in sequence from an object side, an objective optical system, an erecting prism, and an ocular optical system, wherein: in sequence from the object side, the objective optical system includes a first lens group having a positive refracting power and a second lens group having a negative refracting power; in sequence from the object side, the second lens group comprises a positive lens group having a positive refracting power and a negative lens group having a negative refracting power; and an image position can be changed by the negative lens group of the second lens group being displaced in a direction orthogonal to an optical axis.
