Sigma 85mm f/1.2 DG Art Lens
Flagship Ultra-Fast Portrait Prime for Full-Frame Mirrorless Systems – Ultrafast f/1.2 Maximum Aperture, Dual High-Response Linear Actuator (HLA) Autofocus System, Advanced Optical Formula (2 SLD & 3 Aspherical Elements, 17 Elements in 12 Groups), Suppressed Focus Breathing, 13-Blade Rounded Diaphragm for Near-Circular Bokeh, De-Clickable Manual Aperture Ring with Lock Switch, Class-Leading Compact & Lightweight Build (Under 2 lb), Dust- and Splash-Resistant Structure with Water- and Oil-Repellent Front Coating, Standard 82mm Filter Thread
The Sigma 85mm f/1.2 DG Art is a benchmark ultra-fast medium-telephoto prime lens engineered for full-frame mirrorless cameras, setting a standard for resolving power, shallow depth-of-field separation, and optical engineering. Designed for commercial portraiture, high-fashion editorial, wedding photography, fine-art stills, and cinematic video production, it pairs a classic 85mm focal length with a light-gathering f/1.2 maximum aperture. Engineered to overcome the excessive bulk traditionally associated with f/1.2 glass, it stands as the smallest and lightest lens in its class, measuring approximately 3.4 x 4.7 inches and weighing just around 2 lb for handheld mobility on set or in the field.
The optical formula utilizes 17 elements in 12 groups, incorporating two Special Low Dispersion (SLD) elements and three high-precision aspherical elements to suppress chromatic aberrations, spherical distortion, and axial color fringing wide-open at f/1.2. The optical grouping is optimized to minimize focus breathing, preserving consistent framing during cinema focus pulls. A rounded 13-blade diaphragm produces circular out-of-focus highlights and soft background rendering. Autofocus is driven by a Dual HLA (High-response Linear Actuator) motor system, delivering rapid, whisper-quiet, and precise tracking capable of keeping pace with high-speed burst shooting and subject-detection video algorithms. Built for demanding professional environments, the chassis features a dust- and splash-resistant structure, a water- and oil-repellent front coating, a tactile de-clickable and lockable physical aperture ring, customizable AFL control buttons, and a standard 82mm front filter thread.
KEY FEATURES & PERFORMANCE HIGHLIGHTS
Classic 85mm Medium-Telephoto Perspective: Ideal focal length for flattering facial proportions, natural perspective compression, and subject-background isolation.
Ultrafast f/1.2 Maximum Aperture: Provides light gathering for dim ambient lighting alongside thin depth-of-field separation.
Dual HLA Autofocus System: Dual High-response Linear Actuator drive provides rapid, near-silent, and responsive AF tracking for stills and video.
13-Blade Rounded Diaphragm: Generates circular out-of-focus bokeh highlights, maintaining a soft, painterly blur even when stopped down.
Sophisticated 17-Element Optical Architecture: Incorporates 2 SLD and 3 aspherical elements to control aberrations and deliver high contrast across high-megapixel sensors.
Suppressed Focus Breathing: Optical construction stabilizes angle-of-view shifts across focus pulls for professional video and filmmaking applications.
Class-Leading Compact Form Factor: Engineered as the most portable 85mm f/1.2 prime available, measuring just 3.4 x 4.7 inches and weighing only 2 lb.
Professional Tactile Controls: Equipped with a physical clicked/de-clickable aperture ring, aperture ring lock switch, AF/MF switch, and customizable AFL buttons.
All-Weather Reliability: Sealed against dust and moisture throughout the barrel and mount, finished with a protective water- and oil-repellent front fluorine coating.
