135mm/1.4 (A) DG E-Mount Lens (Black) - SIGMA

Description
The Sigma 135mm F1.4 DG/Art is the world´s first 135mm autofocus lens to achieve a maximum aperture of F1.4, providing exceptional expressive capabilities for portrait photography.

Its unparalleled large bokeh and stunning resolution that reproduces 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 be rendered on a whole new level compared to conventional 135mm F1.8 lenses.

Building on the extensive experience gained from developing numerous F1.4 prime lenses, this new 135mm lens from Sigma sets a new standard in portrait photography.

The unparalleled 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, larger than that of the Sigma 105mm F1.4 DG HSM Art, known as "Bokeh Master," and comparable to that of the Sigma 200mm F2 DG OS Sports.

The unique natural perspective of the 135mm, coupled with its stunning bokeh, highlights the subject and creates dimensional portraits that can only be achieved with this lens.

Optical design optimized for natural bokeh
Complete correction of chromatic aberration, common in telephoto lenses, allows you to achieve sharp bokeh without color bleeding.

The design also minimizes vignetting, producing natural, nearly circular bokeh, even at the edges, taking full advantage of the wide-angle aperture.

Sigma´s Craftsmanship Behind Beautiful Bokeh
A 13-blade diaphragm maintains the circular shape of the bokeh, while exceptional precision in processing aspherical lenses further enhances its smoothness.

This beautiful, natural bokeh is the result of Sigma´s expertise, acquired over many years of developing F1.4 prime lenses, and the advanced manufacturing technology cultivated at its Aizu factory.

Sharp Subject Details, Even Wide Open
Four large FLD glass elements are positioned, along with strategically placed high-dispersion glass elements, to completely suppress axial chromatic aberration, which tends to be more pronounced in wide-aperture telephoto lenses. As a result, the lens delivers sharp subject details even when shot wide open, taking full advantage 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 focusing lens groups independently, ensuring consistently high resolution throughout the focusing range.

Dual HLA for Fast and Accurate Autofocus
Each of the two focusing 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 focusing group, the dual HLA system ensures both the high drive required for wide-aperture telephotos and fast and accurate AF performance. This allows even fleeting expressions and fast-moving subjects to be captured with exceptional reliability.

Designed to Minimize Flare and Ghosting
Flare and ghosting, which detract from image quality, are addressed in all incident light conditions, based on Sigma´s most advanced simulation technology and Super Multi-Layer Coating. High backlight resistance allows for sharp, clear images in any lighting conditions.

Various Shooting Assist Functions
The lens is equipped with a dual-location AFL button, which can be assigned to a variety of functions via the menu on select cameras. In addition to the aperture ring, the lens is equipped with an aperture ring lock switch and a click switch to activate and deactivate the click.

Dust- and splash-resistant construction and water- and oil-repellent coating
In addition to a dust- and splash-resistant construction, the front lens element features a water- and oil-repellent coating, allowing photographers to shoot worry-free even in harsh outdoor environments.

Excellent build quality meets Sigma´s Art-line specifications.
Metal components, such as aluminum and magnesium alloys, are combined with engineering-grade plastics, such as 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 required 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 mount for long studio shoots
The lens comes with a lightweight yet robust magnesium alloy tripod mount compatible with Arca-Swiss clips. It offers excellent stability during studio shoots and extended photography, helping photographers maintain focus on their creative expression. The tripod mount is also removable and can be replaced with the supplied protective cover.

Supplied Lens Hood with Push-Button Locking Mechanism
The supplied lens hood is equipped with a push-button locking mechanism for secure attachment and removal. It is made of CFRP, a carbon fiber-reinforced polycarbonate material, making it lightweight and durable.
