A fast f/1.2 lens with a focal length of 56mm (85mm 35mm format equivalent) that delivers beautiful background bokeh so it's ideal for portraiture. The lens' incredible resolving power is thanks to a new optical design featuring 11 elements in 8 groups. Two ED (extra-low dispersion) elements and one double-sided aspherical element are used to control spherical and chromatic aberrations, while a further four of the elements feature convex surfaces to ensure excellent light coverage, even when shooting wide open.
