Zoom lens and image pickup apparatus equipped with same

摘要

There is provided a zoom lens in which the load on the driving system for wobbling operation can easily made low and an image pickup apparatus equipped with the same. A zoom lens in which each of distances between a plurality of lens units changes during zooming from the wide angle end to the telephoto end, includes a focus lens unit that shifts along an optical axis to effect focusing from infinity to a close distance and a plurality of wobbling lens units that wobble after a shift of the focus lens unit at an amplitude smaller than the shift of the focus lens unit in focusing operation, wherein a combination of the wobbling lens units caused to operate changes in the middle of the zooming from the wide angle end to the telephoto end.

1. A zoom lens in which each of distances between a plurality of lens units changes during zooming from the wide angle end to the telephoto end, comprising:
a focus lens unit that shifts along an optical axis to effect focusing from infinity to a close distance; and a plurality of wobbling lens units that wobble after a shift of the focus lens unit at an amplitude smaller than the shift of the focus lens unit in focusing operation, wherein the wobbling lens unit caused to operate is switched in the middle of the zooming from the wide angle end to the telephoto end.
