Revolutionizing portraits with the world’s first 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.
Large bokeh for powerful visual expression
Unmatched large bokeh opens up new expressive possibilities
The most notable feature of the Sigma 135mm F1.4 DG | Art is its extremely large bokeh. The effective aperture diameter of the 135mm F1.4 lens produces exceptional bokeh, which is larger than that of the Sigma 105mm F1.4 DG HSM | Art known as “Bokeh Master”.
The natural perspective unique to 135mm, together with its overwhelming bokeh, highlights the subject and creates dimensional portraits achievable only with this lens.
Optical design optimized to produce the natural bokeh
Thorough correction of chromatic aberration, which is common in telephoto lenses, achieves clear bokeh without color bleeding. The design also minimizes vignetting, rendering natural, near-circular bokeh even at the edges―fully utilizing the wide-open aperture.
Sigma’s craftsmanship behind the beautiful bokeh
A 13-blade diaphragm maintains a circular bokeh shape, while exceptional precision in aspherical lens processing further enhances its smoothness. This beautiful, natural bokeh is the result of Sigma’s know-how gained through development of F1.4 prime lenses over many years and the advanced manufacturing technology cultivated at its Aizu factory.
Precision optics for exquisite portrait detail
Clear subject detail even at maximum aperture
Four large FLD glass elements are positioned, along with strategically placed high-dispersion glass elements to thoroughly suppress axial chromatic aberration, which tends to be more pronounced in large-aperture telephoto lenses. As a result, the lens delivers crisp subject detail even when shot wide open, making full use of the exceptionally shallow depth of field unique to a 135mm F1.4.
Floating focus system for consistent sharpness
A floating focus system moves the two focus lens groups independently, ensuring consistently high resolution across the entire focus range.
Designed to minimize flare and ghosting
Flare and ghosting, which reduce image quality, are addressed under all conditions of incident light, based on the most advanced simulation technology and Sigma’s Super Multi-Layer Coating. High backlight resistance enables clear and sharp images under any lighting conditions.
Fast, accurate autofocus to capture fleeting expressions
Dual HLA for fast, precise autofocus
Each of the two focus groups is driven by its own HLA (High-response Linear Actuator), forming a dual HLA system. By incorporating two distinct types of HLAs, each optimized for the movement range of a focus group, the dual HLA system ensures both the high thrust needed for large-aperture telephoto lenses and fast, precise AF performance. This allows even fleeting expressions and fast-moving subjects to be captured with exceptional reliability.
A wealth of functions for professional use and excellent build quality
Various shooting assist functions
The lens is equipped with an AFL button in two locations, which can be assigned to a range of functions via the menu on selected cameras. In addition to the aperture ring, the lens is equipped with an aperture ring lock switch and a click switch to turn the click on and off.
Dust- and splash-resistant structure and water- and oil-repellent coating
In addition to a dust- and splash-resistant structure, the front element of the lens features a water- and oil-repellent coating, allowing photographers to shoot without concerns even in harsh outdoor environments.
Excellent build quality of Sigma’s Art line specifications
Metal components such as aluminum and magnesium alloys are combined with engineering plastics like TSC, strategically placed throughout the construction. This balances the durability required to support the optical system of a large-diameter lens with the lightweight design necessary for comfortable handling. The Art line offers remarkable rigidity, durability, and build quality for long-term reliability as a tool of expression.
Arca-Swiss compatible tripod socket for long studio shoots
The lens comes with a lightweight yet robust tripod socket made of magnesium alloy, compatible with Arca-Swiss clamps. It provides excellent stability during studio sessions and extended shooting, helping photographers stay focused on their creative expression. The tripod socket is also removable and can be replaced with the supplied protective cover.
