ABSTRACT:
A camera having an optical system which is shiftable to compensate for vibrations affecting the camera, a shift mechanism which shifts the optical system along an axis, and an urging mechanism. The urging mechanism provides an urging force along the axis to urge the optical system and to assist the shift mechanism in shifting the optical system. The urging force of the urging mechanism is approximately 1.5 to 5 times the weight of the optical system. Moreover, a feed screw mechanism includes a male portion and a female portion which cooperate, via a helical groove, to shift the optical system. The feed screw mechanism has an angle of friction and the helical groove has a lead angle that is smaller than the angle of friction.
