Cherished for sports and wildlife applications, the EF 600mm f/4L IS III USM is a Canon L-series super telephoto lens distinguished by its advanced, lightweight design, quick and intuitive handling, and high speed performance. Using fluorite, Super UD, and aspherical elements, both chromatic and spherical aberrations are kept to minimum in order to realize sharp, clear image quality with accurate rendering and color fidelity. Both Super Spectra and Air Sphere Coatings also contribute to color accuracy and helps to control flare and ghosting when working in backlit and harsh lighting conditions.Manufacturer Included Items:Canon EF 600mm f/4L IS III USM LensCanon E-185C Lens CapCanon Lens Dust Cap E (Rear Lens Cap)Canon ET-160 (WIII) Lens HoodCanon LS600 Soft Lens CaseCanon - Drop-In Filter Holder for 52mm Screw-In FiltersStrapBundle Items Include:1 x Canon EF 600mm f/4L IS III 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
