Canon EF 85mm f/1.2L USM AutoFocus Telephoto Lens

With a large maximum aperture of f/1.2, this is the fastest 85mm telephoto lens in its class. One aspherical lens element and two high-refraction elements give sharp images with little flare even at maximum aperture. The floating system corrects coma for high image quality.
