Abstract:
Provided is a zoom lens, including, in order from object side: a positive first unit; a negative second unit; a positive third unit; a negative fourth unit; and a positive fifth unit, in which: intervals between adjacent units are changed during zooming; the first unit is not moved in an optical axis direction for zooming, and the second, third, and fourth units are moved in the optical axis direction during zooming; the fourth unit is moved in the optical axis direction during focusing; the third unit includes, in order from the object side, a positive first subunit, and a positive second subunit, and the second subunit is moved during image stabilization in a direction having a component in a direction orthogonal to the optical axis; and focal lengths of the first, third, fourth unit, and the zoom lens at a wide angle end are appropriately set.
