Minimum focal length of 17mm—large-aperture standard zoom
lens for DSLR cameras
This large-aperture standard zoom lens covers a wide-angle focal length of
17mm. Ideal for travel and other situations where you want mobility, this lens
has a compact body and is only 91.8mm long. Two FLD glass elements and
three aspherical lens elements correct aberrations, while the Super Multi-Lay-
er Coating minimizes flare and ghosting. Plentiful peripheral brightness as-
sures sharp, high-contrast images all the way to the maximum aperture. The
HSM provides fast and quiet autofocusing.
