Prized for portraiture, the EF 85mm f/1.8 USM from Canon is a short-telephoto prime characterized by its slightly compressed perspective for achieving flattering results. Its bright f/1.8 maximum aperture also enables isolating subjects and working with shallow depth of field techniques, and further benefits working in low-light conditions. Helping to achieve high color fidelity and contrast, a Super Spectra coating has been applied to individual elements and serves to minimize reflections, lens flare and ghosting. Additionally, a ring-type USM is employed to deliver quick and quiet autofocus performance along with full-time manual focus control.
