A super telephoto lens with a large aperture of f/4.5. An artificial crystal fluorite lens element(second) and a UD glass lens element(4th) having ultra-low dispersion minimize the secondary spectrum and achieve high resolution and high contrast without color blur or flare by axial chromatic aberration at the edges of the subject. The rear focusing system is adopted. With the marketing of this lens, naming of S.S.C.(Super Spectra Coating) and S.C. (Spectra Coating) were discontinued. Lenses employing special optical elements, such as fluorite elements, UD(Ultra-low Dispersion) glass elements and ground and polished glass aspherical lens elements, came to be called “L” (Luxury) lenses. After this lens, “L” becomes a synonym for Canon’s high performance lenses.
