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.
