Abstract
An antivibration device includes a correcting optical system to correct shake by moving at least a part of a photographic optical system, a support member to support the correcting optical system, and a lens mount member to support the shake correction mechanism. A shielding member is further provided on at least either the support member or the lens mount member so as to keep dust and other potentially damaging airborne material from entering the shake correction mechanism. The shielding member is provided so as to extend substantially parallel to the optical axis of the photographic optical system.
