Distinguished by its incredibly fast design and IS Cap,abilities, the EF 85mm f/1.4L IS
USM from canon is a short telephoto prime well-suited to portraiture
applications. As an L-series lens, it is characterised by a sophisticated
optical layout that includes one glass moulded aspherical element to greatly
reduce spherical aberrations and distortion for improved sharpness and clarity.
Individual elements also feature an Air Sphere coating (ASC) to suppress lens
flare and ghosting for greater contrast and colour fidelity in backlit
situations.
