Full-Frame Portrait Lens. The Sigma 85mm f/1.4 gives users a much-needed Art-Series portrait lens. Dedicated portrait shooters, wedding photographers, event photographers, and anybody who needs a short tele lens will all benefit. The fast f/1.4 aperture allows great low-light capability as well as a very shallow depth-of-field. Using a APS-C sensor camera? You’ll have a focal length equivalent to 136mm.

High Image Quality. As a part of Sigma’s Art lens line, this lens goes through Sigma’s rigorous A1 testing to ensure high image quality. The 85mm f/1.4’s optics are quite impressive. Two SLD glass elements, one high-refractive index element, and one aspherical element correct for chromatic aberrations throughout the entire focusing range, while ensuring high image sharpness, clarity, and contrast. A Super Multi-Layer Coating minimizes lens flare and ghosting to help produce high-contrast, color-accurate images.

Hyper Sonic Motor Autofocus System. The HSM autofocus system provides fast, smooth, and quiet operation in a wide variety of shooting situations. You can also manually override the autofocus motor at any time by rotating the focusing ring, giving you quick fine-tuning ability.

Dock Compatible. This lens is compatible with the Sigma USB Dock for Canon EF Lenses (separate rental item), allowing you to adjust the focus limiter, autofocus speed, and microfocus settings through the Sigma Optimization Pro software.
