An upgraded version of the EF85mm F/1.2L USM, widely deemed the “gold standard” for professional portrait work, this lens is the brightest in its class and offers beautiful out-of-focus effects. By virtue of its precisely ground aspherical lens, which adeptly compensates for spherical aberrations and other distortions, this lens displays exquisite detail and high contrast even at f/1.2. And with the incorporation of a floating lens mechanism, aberration fluctuations are substantially reduced at short and medium distance shots to ensure extremely sharp, quality images consistently at all shooting distances. We have also dramatically sped up AF performance in response to requests from professionals. A faster CPU and optimized AF algorithm allow the lens to focus instantaneously for reliable capture of fleeting photo opportunities. This lens is even more pleasant to use for portrait work because of the very shallow depth of field at f/1.2, coupled with full-time manual focusing for fine adjustment. Furthermore, Canon effectively reduced the flaring and ghosting common with digital cameras by optimizing internal lens placement and coatings. A circular aperture is also used to maximize the wonderful defocusing attributes of the lens at the maximum f/1.2 aperture. All told, this is the one lens that can meet the toughest demands of professional photographers, whether shooting female portraits with a masterful blur effect or natural scenes in natural lighting.
