The Canon EF 85mm f/1.2L II USM Autofocus Lens is a fast lens
that delivers superb optical performance. A maximum aperture of f/1.2
makes it the professional's choice for shooting without flash in low
light conditions. The large aperture also provides fine control over
depth of field for compelling portrait photography.
Retaining the impressive optical performance and large aperture of its
predecessor, this medium telephoto lens has been improved with 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.
