摘要： A lens driving device has first and second driving units for moving first and second lens holders supporting first and second sets of lens elements in an optical axis direction, respectively. The first and second driving units each have a motor, a gear fitted around an output shaft of the motor, a lead screw rotated by the gear, and a nut fitted around the lead screw. The output shafts of the first and second motors overlap each other in their axial direction. The first and second driving units move the first and second lens holders in the optical axis direction via the respective nuts moving in the optical axis direction. An image pickup plane side end face of the motor of the first driving unit is positioned more to the image pickup plane side than a position most to the subject side of the second lens holder is.

摘要： A camera having an automatic focus (AF) and an image-shake compensating device. The automatic focus device includes a phase-shift detector having photodetecting means (7,8,18) for receiving light passing through different portions (3,4) of the main imaging lens pupil and means for detecting the focus condition of the main imaging lens (10) from the light distributions received by the photodetecting means.
The image-shake compensating device includes vibration detecting means (26) and actuating means (28) for either displacing a lens (10b) perpendicularly to the optical axis of the main imaging lens (10) or pivoting the whole lens system about an axis perpendicular to the optical axis.
The camera includes also means (27) for detecting the de-alignment of the lens system caused by the actuating means, memory means (22) for storing aberration information in dependence of the lens system de-alignment and means (19,21) for calculating the amount of movement of the focusing lens along the optical axis on the basis of the detected focus condition and aberration information read out from the memory means.
The system is capable of achieving proper focusing by correcting the focusing position taking into account the different spectral sensitivity of photographic material and photodetectors (7,8,18) even when additional chromatic or spherical aberrations are produced by the image-shake compensating device.
