ABSTRACT:
There is provided binoculars which include a pair of observation optical systems each having an objective optical system, an erecting optical system and an eyepiece optical system. The binoculars include a focusing mechanism that is used to move a part of observation optical systems for focusing, a convergence value compensating mechanism that compensates for a convergence value by displacing displaceable optical elements which are at least parts of the objective optical systems, respectively, in association with actuation of the focusing mechanism, and a light shielding mechanism configured to shield light for preventing light from entering through a clearance caused in accordance with displacement of the displaceable optical elements by actuation of the convergence value compensating mechanism.
