PHOTOGRAPHIC LENS PROVIDED WITH CAMERA SHAKE CORRECTING FUNCTION

摘要

PROBLEM TO BE SOLVED: To correct camera shake in a wide range with a small driving quantity by proving a reflection mirror at a part of an optical system and driving the reflection mirror eccentrically thereby correcting the camera shake. SOLUTION: In this the photographic lens, a luminous flux from an object through a lens 4 is bent by a main mirror 3 and a sub mirror 1 so that it may goes backward and forward in the same space. An actuator 2 as a driving means for making the sub mirror 1 in an eccentric state in order to correct the camera shake is installed on the lens 4. The actuator 2 is constituted of two actuators. Besides, a lens control unit 8 for communicating with a body CPU 9 in a camera body BO is installed in a reflection telephoto lens LS. The actuator 2 is driven by the lens control unit 8 based on the camera shake data detected by an X-sensor unit 6 and a Y-sensor unit 7. The camera shake is corrected by driving the sub-mirror 1 eccentrically by the actuator 2.
