Sigma AF 85mm f/1.4 DG HSM Art Canon is a professional portrait lens for full-frame Canon EF-mount cameras, suitable for creative and artistic shooting. It features a fast f/1.4 rounded 9-blade diaphragm for extremely shallow depth of field and smooth bokeh. The f/1.4 aperture is ideal for low light and provides enhanced focus control when shallow depth of field is required. The optical design includes three special glass elements: two SLD elements and one element with anomalous partial dispersion and high refraction. Low-dispersion elements correct chromatic aberration, and a molded glass aspherical lens corrects spherical aberration. This construction helps limit vignetting and provides high sharpness regardless of focus point or aperture. Super Multi-Layer Coating minimizes flare and ghosting, delivering accurate color reproduction, contrast across the frame, and high resolution. The HSM ultrasonic motor provides fast, quiet, accurate autofocus, and the large focus ring supports precise manual focus. Included: Sigma AF 85mm f/1.4 DG HSM Art Canon lens, front cap, rear cap, hood, pouch.
