Sigma 20-60mm f/2.8-4 DG Contemporary Lens
Ultra-Compact Wide-to-Normal Full-Frame Zoom – Dynamic 20-60mm Focal Range, Fast f/2.8 Starting Maximum Aperture, High-Response Linear Actuator (HLA) Autofocus Motor, Near Half-Macro Performance (1:2.3 Reproduction Ratio & 6.2″ Minimum Focus), Advanced Optical Formula (3 SLD & 3 Aspherical Elements), Suppressed Focus Breathing for Video, Dust- and Splash-Resistant Construction with Water- and Oil-Repellent Front Coating, Lightweight 13.2 oz Travel Footprint, Standard 67mm Filter Thread
The Sigma 20-60mm f/2.8-4 DG Contemporary is an ultra-compact, highly versatile standard zoom lens engineered for full-frame mirrorless cameras. Expanding beyond conventional 24mm or 28mm standard zooms, it begins at an ultra-wide 20mm, providing an expansive field of view for architecture, sweeping landscapes, dynamic vlogging, and tight interior spaces, while smoothly extending to a natural 60mm portrait and documentary perspective. Combining an ultra-portable profile of just 2.8 x 3.5 inches and weighing only 13.2 oz, it delivers a balance of everyday mobility, optical resolution, and low-light versatility with a bright f/2.8 aperture at the wide end.
The sophisticated optical formula consists of 15 elements in 13 groups, incorporating three Special Low Dispersion (SLD) elements and three high-precision aspherical elements to suppress chromatic aberrations, distortion, and field curvature across the entire zoom range. Designed to meet hybrid photo and video demands, the optical grouping minimizes focus breathing, maintaining framing stability during focus transitions. Autofocus is driven by a rapid, whisper-quiet High-response Linear Actuator (HLA) motor system, ensuring swift and precise focus tracking for fast-moving subjects and fluid video production. The lens also features near half-macro capabilities, focusing as close as 6.2 inches at 28mm and achieving a maximum reproduction ratio of 1:2.3 at 35mm. Built for outdoor reliability, the chassis incorporates a dust- and splash-resistant structure, a water- and oil-repellent front coating, and a standard 67mm front filter thread.
KEY FEATURES & PERFORMANCE HIGHLIGHTS
Dynamic 20-60mm Focal Range: Unique wide-to-normal zoom span covers dramatic ultra-wide vistas, street scenes, tabletop close-ups, and natural standard perspectives.
Fast f/2.8 Starting Aperture: Bright f/2.8 maximum aperture at 20mm delivers enhanced light-gathering capability and depth-of-field control in dim lighting.
Near Half-Macro Capabilities: Focuses down to 6.2 inches at 28mm with a high 1:2.3 maximum reproduction ratio at 35mm for detailed close-up imagery.
HLA Linear Autofocus Motor: High-response Linear Actuator drive provides rapid, smooth, and near-silent autofocus tracking optimized for stills and cinema.
Advanced Optical Architecture: 3 SLD and 3 aspherical elements ensure edge-to-edge sharpness and high contrast while suppressing spherical and chromatic aberrations.
Suppressed Focus Breathing: Optical construction reduces angle-of-view shifts during racking focus, providing a stable frame for video production.
Ultra-Compact & Lightweight Design: Measures just 2.8 x 3.5 inches and weighs only 13.2 oz, making it an ideal companion for gimbals, travel kits, and all-day carry.
All-Weather Reliability: Sealed against dust and water splashes throughout the barrel, completed by a protective water- and oil-repellent front element coating.
Standard 67mm Filter Thread: Compatible with widely available front filters, NDs, and circular polarizers.
