Canon EF 16-35mm f/2.8L III USM Lens OverviewCharacterized by a revamped optical design, the EF 16-35mm f/2.8L III USM from Canon is a workhorse wide-angle zoom and member of the well-regarded L-series of lenses. Featuring a series of specialized elements, this lens utilizes a trio of aspherical elements and two ultra-low dispersion glass elements to control a variety of aberrations for high sharpness and clarity. Both SWC and ASC coatings have also been applied to the elements in order to reduce lens flare and ghosting for increased contrast and color accuracy.What's In The BoxCanon EF 16-35mm f/2.8L III USM LensE-82 II 82mm Lens CapLens Dust Cap E (Rear)EW-88D Lens HoodLP1222 Lens PouchExtra Bundle Items:1 x Padded Carrying Case (Protect Your Gear!)1 x Lens Pouch Sleeve (for Medium Sized Lenses)1 x 82mm 3 Piece Filter Kit Includes: UV, Circular Polarizer and Fluorescent Filter and Hard Case1 x Lens Pen Cleaner1 x High Quality Dust Blower1 x Lens Cleaning Solution1 x Blower Brush1 x Lens Tissue Paper5 x Cotton Swabs1 x Deluxe 70" Monopod1 x Lens Cap Keeper (Dont Lose your Caps!)1 x MicroFiber Cloth1 x Large Cleaning Bottle for LCD Monitors2 Year Extended Warranty Included (Replaces Manufacturer Warranty)
