<p>A zoom lens includes, in order from an object side to an image side, a front lens group including a first lens unit having positive refractive power and a second lens unit having refractive power, and a rear lens group including a plurality of lens units. The second lens unit includes a reflective member configured to bend an optical path. At least the first lens unit and at least two lens units of the rear lens group move during zooming. The second lens unit does not move for zooming. A reflection unit including the reflective member moves perpendicularly to an optical axis of the front lens group during retraction. At least part of the front lens group is retractable into a space caused by movement of the reflection unit. A focal length f2 of the second lens unit and a focal length ft of the entire zoom lens at a telephoto end are appropriately set.</p> |
