ZOOM LENS AND IMAGE PICKUP APPARATUS
A zoom lens (101) includes, in order from an object side, a first lens group (F) of which at least a part moves for focusing, a plurality of lens groups (LZ) which moves in zooming, an aperture stop (SP), and a final lens group (R) which does not move for zooming. The final lens group (R) includes a...

Zusammenfassung: | A zoom lens (101) includes, in order from an object side, a first lens group (F) of which at least a part moves for focusing, a plurality of lens groups (LZ) which moves in zooming, an aperture stop (SP), and a final lens group (R) which does not move for zooming. The final lens group (R) includes a separation element (PR) for separating an incident light thereon into a transmitted light and a reflected light, a relay unit LR having a positive refractive power on which the transmitted light is incident, and a relay unit LA having a positive refractive power on which the reflected light is incident. An inequality about Fwp/Fw is satisfied, where Fw is a focal length at a wide angle end of the zoom lens (101) via the relay unit LR and FwP is a focal length at the wide angle end of the zoom lens (101) via the relay unit LA. |
