Retaining the impressive optical performance and large aperture
of the original 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, which is ideal for portraits and weddings. The
floating optical system, which includes an aspherical lens element,
suppresses aberrations and ensures excellent imaging performance.
