This lens has 15 elements in 11 groups, including two "F" Low Dispersion (FLD) elements, five Special Low Dispersion (SLD) elements. Two aspherical elements are featured to significantly reduce spherical & chromatic aberrations, & to limit distortion for sharp, clean, & evenly illuminated images. A Super Multi-Layer Coating has been applied to minimize flaring, ghosting, & surface reflections, as well as to provide increased contrast & color accuracy. The lens' wide focal length & consistency of high quality images makes this lens especially suitable for landscape, architectural, interior, & astrophotography applications. The fast f/1.4 maximum aperture makes it ideal for natural & low-light shooting. Its Hyper Sonic Motor, which provides smooth, fast, & near-silent autofocus performance. The focusing motor also allows for full-time manual focus at any time by rotating the focus ring. The focus ring allows for refined manual control & focusing as close as 10.9".

Elements / Groups: 15 Elements in 11 Groups
Elements / Groups:
The individual pieces of glass that form the overall optical construction. Most lenses have between four and eleven elements to bend the light rays to ensure a perfectly formed image appears on the light sensitive surface, such as a film or CCD. The elements are arranged in groups and may be seen in specification sheets as, for example, 6 elements in 4 groups. That configuration may have two single elements and the other four grouped in pairs.
