Abstract:
The attachment lens device AL, 12 can be mounted between a master lens ML, 12 having a focusing lens group that moves in an optical axis direction for focusing purposes and a camera body 11 having an imaging device. The attachment lens device AL, 12 comprises a communication portion 35, 135 communicatable with the master lens ML, 12 and the camera body 11, a wobbling lens group LW capable of reciprocally wobbling in the optical axis direction for detecting a direction of moving the wobbling lens group, and a wobbling drive portion 125 for driving the wobbling lens group Lw.
