Classic portrait-length prime, this 85mm f/1.2 lens is designed for full-frame Canon EF-mount DSLRs Fast f/1.2 maximum aperture offers a high degree of control over depth of field for working with selective focus and shallow depth of field techniques It also benefits working in low-light conditions with shorter shutter speeds. One aspherical element and two high refractive index elements are featured in the optical design to control spherical aberrations for improved clarity and sharpness throughout the aperture range An Ultra Multi-Coating has been applied to individual elements to minimize ghosting and flare for increased contrast and color neutrality when working in strong lighting conditions Manual focus design permits working with subjects as close as 2.6' away Nine-blade diaphragm contributes to a smooth and pleasing bokeh quality Aluminum alloy housing is both durable and lightweight
