Revolutionizing portraits with the world’s first*1 AF 135mm F1.4.
The Sigma 135mm F1.4 DG | Art is the world’s first 135mm autofocus lens to achieve a maximum aperture of F1.4, delivering exceptional expressive capabilities for portrait photography.
Its unrivaled large bokeh and stunning resolution that renders every detail create an extraordinary sense of depth and dimensionality.
The natural perspective and moderate shooting distance unique to 135mm, combined with the rich bokeh of the bright F1.4 aperture, make the subject stand out and render on an entirely different level compared to conventional 135mm F1.8 lenses. Built on extensive expertise gained from developing numerous F1.4 prime lenses, this new 135mm lens from Sigma sets a new standard in portrait photography.

Versatile Lens Construction

• The lens features an assignable AFL button for custom functions as well as a focus mode switch and aperture ring lock. The aperture ring can be changed from clicked to declicked for smooth video operation.
• A water- and oil-repellent coating on the front lens element makes it possible to shoot in harsh outdoor environments, while the dust- and splash-resistant construction keeps the internal elements protected.
• Included is a removable tripod socket compatible with Arca-type clamps for increased stability due to the weight of the lens. The tripod socket can be replaced with the supplied protective cover.

Complex Optical Design

• Sigma combines two aspherical elements and four F Low Dispersion (FLD) elements to ensure clarity from wide open at f/1.4 through the rest of the aperture range.
• A total of 17 elements in 13 groups, as well as a 13-blade rounded diaphragm, create beautiful circular bokeh, minimizing vignetting and color bleeding even at the edges.
• Sigma's Super Multi-Layer Coating is used to optimize backlight resistance, minimizing potential lens flare and ghosting.

Powerful Focusing System

• No longer purely for photography, the lens elements have been optimized to reduce focus breathing, making it a strong choice for professional video use.
• Powered by Sigma's dual HLA (High-Response Linear Actuator) focusing system for fast and quiet autofocusing throughout the entire telephoto focusing range, allowing fast-moving subjects to be captured reliably.
