This lens sports a Voice Coil Motor (VCM) for fast floating rear focus and a Nano USM for quick and quiet floating autofocus performance. Its optical design incorporates specially developed elements that help to nearly eliminate chromatic aberrations and color fringing for notable clarity and color accuracy. Two ultra-low dispersion elements and two aspherical elements are also featured to further control various aberrations and distortion for great sharpness and resolution. Its durable physical construction is dust- and moisture-sealed with ASC (Air Sphere Coating), SSC (Super Spectra Coating), and Fluorine coatings for use in any environment and to prevent ghosting and flares.
