ABSTRACT:
A binocular is provided with a hand-vibration compensation system. The hand-vibration compensation system includes an arm member which rotatable about a rotation axis extending in parallel with the optical axes of the pair of telescopic optical systems of the binocular. Compensation lenses for shifting images are held at the end portions of the arm. It should be noted that the rotation axis of the arm is located between the optical axes of the pair of telescopic optical systems, and more importantly, the arm is substantially equally balanced at the rotation axis thereof. The arm is driven to rotate about the rotation axis by an actuator in accordance with a hand-vibration applied to the binocular.
