The zoom lens has a focusing ring on the front side and a zoom ring on the rear side. Turn the zoom ring to set the desired angle of view (lens focal length).

"Memo:

The focusing point may shift slightly by changing the focal length. First adjust the zoom and then adjust focus.

The focusing index on the zoom lens is set to match the focus point when the focal length is at telephoto. The focusing index may not match the focus point for other focal lengths.

About the zoom ring

Turn the zoom ring clockwise for telephoto and counterclockwise for wide-angle.
