Canon 85mm L Series:
Canon EF 85mm f/1.2L USM, this new medium telephoto lens uses a Ring-type USM, high-speed CPU and optimized algorithms to achieve an autofocus speed approximately 1.8x faster than the original. The high-speed AF and circular aperture create a shallow depth-of-field that brings attention to the subject and blurs the background. Mixing a short-telephoto focal length with a bright maximum aperture, the EF 85mm f/1.2L II USM is a Canon L-series lens well-suited for portraiture. The impressively fast f/1.2 maximum aperture affords a great degree of control over depth of field for isolating subjects and producing desirable selective focus effects. Complementing these qualities is a sophisticated design that includes one aspherical element to suppress spherical aberrations and notable sharpness and clarity, and a floating optical system is used that maintains image quality throughout the focusing range. A Super Spectra coating has also been applied to limit flare and ghosting and promote greater contrast and color accuracy in a variety of lighting conditions. Complementing the imaging attributes, a ring-type USM is employed to deliver quick and quiet autofocus performance along with full-time manual focus control.
