Canon EF 85mm f/1.2L II USM review
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.
