inside the shake reduction unit inside the innovative pentax shake reduction mechanism two angular velocity sensors are used to detect the amount and direction of camera shake the data accumulated by these sensors is transmitted to the camera s cpu to instantly calculate the vertical and horizontal shift levels required to compensate for camera shake the image sensor is then shifted at the optimum levels using magnetic force generated by the permanent magnets on the front plate and the electrical magnets on the center plate since this mechanism does not require a mechanical guiding device it is free of power loss for quick response and speedy operation the image sensor is firmly supported by the three ball bearings installed on the back plate for pinpoint positioning center plate image sensor back plate position support ball bearing position sensor electrical magnet permanent magnets front plate
