Including a hood, this medium telephoto zoom lens transitions from 63mm to 126.55mm, with a 35mm equivalent focal length, offers a f/4.5 maximum aperture, and features autofocus extending down to f/32. Improving picture quality, it benefits from multiple low-dispersion glass elements and Super Multi Coating, which blocks out flare and ghosting.

Focus as close as 3.3 feet when using this lens, which gives consistency to out-of-focus areas with an eight-blade diaphragm. Photographers may add 77mm filters with the front thread and, when the hood is attached, can easily adjust all by turning the front of the lens.
