ABSTRACT:
Disclosed is an image-taking lens system, with which the optimum image-forming position can be detected accurately regardless of whether an auxiliary lens system is inserted or not, and with little blurring of the image on the output screen during wobbling. The image-taking lens system includes a light amount adjustment stop; a relay lens unit having an image-forming action; a wobbling lens unit arranged within the relay lens unit, the wobbling lens unit being driven by an amplitude in an optical axis direction; and an auxiliary lens system which can be inserted into and removed from the relay lens unit, the auxiliary lens system shifting a focal length of the overall image-taking lens system. The amplitude by which the wobbling lens unit is driven is set depending on whether the auxiliary lens system is inserted or removed.
