Wide-angle zoom lens, 16-35mm focal length, F4 aperture. - Brand: SONY - Model Name: FE PZ 16-35mm F4 G - Included items: Lens case, instruction manual, lens hood, box, aftermarket lens protector - Focal Length: 16-35mm - Aperture: F4 Thank you for viewing. *All included items are present. This lens has been used infrequently. As you can see in the photos, I believe this is a super-mint lens with no visible scratches (amateur inspection). There are no defects associated with use. An optional lens protector is also included. I am selling this because I purchased a different lens and no longer use this one. I have always stored it carefully in a dehumidified storage cabinet. Returns after purchase are not accepted due to the risk of product substitution.
