Covering a versatile wide-angle focal length range, the RF 15-35mm f/2.8L IS USM from Canon is also characterized by its bright f/2.8 constant maximum aperture. This bright design enables working in available light conditions and also affords greater control over depth of field. The range of wide focal lengths suits working in a variety of situations, from landscape to documentary shooting, and this zoom is complemented by an advanced optical design that greatly reduces color fringing and distortion for high clarity and sharpness. An Air-Sphere coating has also been applied to reduce flare and ghosting for improved contrast and color fidelity when working in bright conditions.Included:Canon RF 15-35mm f/2.8L IS USM LensManufacturer Accessories:Front Lens CapLens Dust Cap E (Rear)Lens HoodLens CaseBundle Accessories:SanDisk Extreme Pro 64gb SD Card6pc Graduated Color Filter Set3 Piece Multi Coated HD Filter Kit (UV, CPL, FLD)Lens Cap KeeperHigh Quality Lens Cleaning PenHigh Quality Dust BlowerStarter Cleaning KitMicrofiber Cleaning Cloth
