Its unrivalled 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.

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*1 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,” and is comparable to that of the Sigma 200mm F2 DG OS | Sports.

The natural perspective unique to 135mm, together with its overwhelming bokeh, highlights the subject and creates dimensional portraits achievable only with this lens.

*1 The effective aperture diameter is calculated by dividing the focal length by the F-number. It refers to the diameter of the light beam that forms an image at the centre of the image sensor. A larger effective aperture results in a shallower depth of field and more pronounced bokeh.

Optical design optimised to produce the natural bokeh

Thorough correction of chromatic aberration, which is common in telephoto lenses, achieves clear bokeh without colour bleeding.

The design also minimises vignetting, rendering natural, near-circular bokeh even at the edges?fully utilising 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.

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 minimise 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.

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 optimised 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.

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*1 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.

*1 The structure is designed to be dust- and splash- resistant, but not waterproof. Be careful not to bring the lens in contact with a large amount of water. Water inside the lens may cause major damage and even render the lens unrepairable.

Excellent build quality of Sigma’s Art line specifications

Metal components such as aluminium and magnesium alloys are combined with engineering plastics like TSC*2, 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.

*2 TSC (Thermally Stable Composite) is a type of polycarbonate with a thermal expansion rate similar to that of aluminium. It has a high affinity to metal parts, which contributes to high quality product manufacturing.

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.

Supplied hood with a button-type locking mechanism

The supplied hood is equipped with a button-type locking mechanism for secure attachment and removal. It is constructed from CFRP, a polycarbonate material reinforced with carbon fibre, making it both lightweight and durable.

Made in Japan

All Sigma cameras and lenses are designed, manufactured and assembled at their sole factory at Aizu in Japan. This domestic production model is unusual in today’s industry, with most imaging companies opting to outsource to other countries to reduce costs. But SIGMA believes that keeping virtually all manufacturing, processing and assembly in Aizu is essential for creating innovative, carefully thought-out and impeccably constructed products that meet the high standards demanded by professional photographers and film-makers around the world.
