Bring your photographic subjects closer with this Canon EF 300mm f/2.8L IS USM Telephoto Lens. The Optical system is designed with a maximum Aperture of f/2.8. One fluorite element and two UD-glass elements effectively correct aberrations resulting in sharp and excellent delineation. The ring USM and an improved AF drive Algorithm make the AF speed the fastest in the world when used with the EOS-1v and EOS-3.
