Canon USA Authorized. Package Contents: Canon EF 16-35mm f/2.8L III USM lens, Canon EOS 200ES Shoulder Bag, 64GB Extreme PRO UHS-I SDXC memory card. Built for demanding photographers, the Canon EF 16-35mm f/2.8L III USM is a professional ultra-wide zoom that delivers consistent, high-quality results across the entire frame. Its constant f/2.8 aperture provides reliable exposure and strong low-light performance, making the lens well suited to landscapes, architecture, interiors, event photography, weddings, and astro work. Optical design highlights include three aspherical elements and two ultra-low dispersion elements to reduce chromatic and spherical aberrations, yielding sharp detail from center to edge and faithful color rendering with minimal distortion. Canon’s Subwavelength Coating (SWC) and Air Sphere Coating (ASC) work together to cut flare and ghosting, helping retain contrast and color accuracy in difficult lighting. The rounded nine-blade diaphragm produces pleasing out-of-focus highlights for smooth bokeh and enhanced subject separation. Autofocus is driven by a ring-type Ultrasonic Motor (USM) that focuses quickly and quietly and supports full-time manual focus override. Rugged L-Series construction with weather sealing ensures durability in challenging conditions, while fluorine coatings on the front and rear elements help repel dust, fingerprints, and moisture to keep the optics clean in the field.
