A truly versatile wide-angle zoom featuring an advanced optical design and constant f/4 maximum aperture, the Canon EF 11-24mm f/4L USM Lens is a member of the esteemed L-series of lenses designed for full-frame EOS DSLRs. One Super UD element and one UD element offer a significant reduction in chromatic aberrations while four aspherical elements help to minimize distortions throughout the zoom range and provide consistent edge-to-edge sharpness and illumination. Both SWC and ASC coatings have been applied to the elements in order to reduce lens flare and ghosting for increased contrast and color accuracy. Ideally suited for landscape and architectural photography, this lens covers ultra-wide to wide-angle perspectives and backs up its versatile zoom range with sophisticated optical components and intuitive handling.Manufacturer Included Items:Canon EF 11-24mm f/4L USM LensCanon Lens Cap for EF 11-24mm f/4L USMCanon Lens Dust Cap E (Rear Lens Cap)Canon LP1424 Lens Case for Canon EF 70-300mm f/4-5.6L IS USM Telephoto LensBundle Items Include:1 x Canon EF 11-24mm f/4L USM Lens1 x Pro Sling Backpack1 x SanDisk 64GB Ultra SDXC Memory Card1 x Memory Card Reader1 x 12_inch Flexible Tripod1 x Memory Card Wallet1 x Lens Cap Keeper1 x Cleaning Kit1 x Hand Strap
