ART
35mm F1.4 DG II

Exceptional resolution across the entire frame from maximum aperture

Built on Sigma’s latest optical design technology, the completely redesigned 15-element, 12-group construction delivers extraordinarily detailed rendering that surpasses previous generations of 35mm F1.4 Art line lenses. By incorporating new glass materials that were previously difficult to process, together with four high-precision aspherical elements and two SLD glass elements, the lens thoroughly suppresses aberrations, particularly axial chromatic aberration, which is often prominent in large-aperture lenses.
Sigma’s rigorous Art line standards ensure outstanding resolution across the entire frame, even at maximum aperture.

Rich and beautiful bokeh without color bleeding

By thoroughly correcting axial chromatic aberration, the lens suppresses color fringing not only in the in-focus plane but also in out-of-focus areas, producing beautifully natural bokeh. The lens features an 11-blade rounded diaphragm, which maintains a round shape even when stopping down from maximum aperture. In addition, by refining the surface accuracy of the aspherical elements to the highest level, the lens enables smooth and beautifully round bokeh.

Newly developed AAC (Advanced Amorphous Coating)

The newly developed AAC (Advanced Amorphous Coating) features a low-refractive-index amorphous layer that dramatically reduces reflections responsible for ghosting and flare, delivering exceptionally clear, high-contrast image quality.

Pursuing uncompromising compactness and lightness

By adopting a floating focus system, the lens achieves both enhanced optical performance and a more compact, lightweight design. Compared to the previous model, it is approximately 14% shorter and 20% lighter. The mechanical design incorporates numerous space-saving innovations down to the smallest details, ensuring truly uncompromising compactness and portability. This agility empowers photographers to pursue their creative vision.

Fast and quiet autofocusing with dual HLA system

The lens employs Sigma’s dual HLA (High-response Linear Actuator) system, which drives its large and heavy focus group with high power and speed. Even as a large-aperture lens where the focus group tends to become heavier, it delivers fast, accurate, and quiet AF for both stills and video—ensuring that the user can capture decisive moments reliably.

A long-lasting, reliable tool for photographic expression

By assembling high-precision parts made of aluminum, TSC*1, and other materials, the lens achieves the high level of rigidity, durability, and build quality expected of the Art line without compromising portability. As a photographic tool, it offers the reliability needed for long-term use.

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

Various shooting assist functions and focus breathing design

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*1 and a click switch to turn the click on and off.

Optimization of the focus group arrangement and aspherical shape significantly suppresses focus breathing. The change in angle of view due to focus shift is minimized, creating a natural-looking focus shift when recording video.

*1. If you turn it on in position A, the aperture ring will be locked in position A. If you turn it on in a position other than A, it will be locked in the range from open to minimum aperture.

Protection and Hood mechanism

In addition to a dust- and splash-resistant structure*1, the frontmost surface of the lens has a water- and oil-repellent coating applied. The Sigma 35mm F1.4 DG II | Art comes with a dedicated petal-type hood that shields the front element from stray light with a locking mechanism.
