THE NEW SIGMA 35mm F1.4 DG II | ART
— BUILT ON A LEGACY, AND THE FINEST YET
The 35mm F1.4 lens has always held a special place in the hearts of photographers. The brand-new Sigma 35mm F1.4 DG II | Art builds on the legacy of Sigma’s 35mm F1.4 Art line and sets a new benchmark with its unmatched optical performance.
The journey began in 2012 with the Sigma 35mm F1.4 DG HSM | Art, the very first lens in Sigma’s Art line. With unprecedented resolving power, the lens made a lasting impact on the photography world, redefining what an F1.4 lens could achieve—a milestone still celebrated today.
In 2021, the 35mm F1.4 DG DN | Art leveraged the advantage of a short flange-back design to significantly improve corner performance and push optical standards even further.
And now, the Sigma 35mm F1.4 DG II | Art stands at the pinnacle as the finest 35mm F1.4 in Sigma’s history. With class-leading optical performance, a refined, compact, and lightweight design, and high-speed AF driven by Dual HLA, this lens embodies years of Sigma’s technology and passion―once again setting a new benchmark in photography.

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, TSC1, 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
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 switch1 and a click switch to turn the click on and off.
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, and it will not be possible to turn it to position A.
Designed to minimize focus breathing
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.
Dust- and splash-resistant structure1 and water- and oil-repellent coating
In addition to a dust- and splash-resistant structure, the frontmost surface of the lens has a water- and oil-repellent coating applied, so that the lens can be used safely even in harsh outdoor environments.
1. The product is designed to be dust- and splash-resistant but is not waterproof. When using the lens near water, etc., take care not to allow large amounts of water to splash on it. If water gets inside the lens, it may cause a major malfunction and render the lens unrepairable.
Petal-type hood with locking mechanism
The Sigma 35mm F1.4 DG II | Art comes with a dedicated petal-type hood that shields the front element from stray light to reduce the chances of unwanted flare. The hood attaches securely to the lens with a locking mechanism.

MTF CHART
There are two types of MTF chart. One considers the diffraction quality of light, which is called "Diffraction MTF", and the other, "Geometrical MTF" does not.
The quality of light appears in the diffracted light, and becomes more distinct as the F value gets bigger, resulting in lower image quality. Also, diffracted light exists at every aperture, which is why Sigma has been releasing Diffraction MTF data from the beginning since it is very close to the actual image data.
The advantage of using "Geometric MTF" data is that it is easy to measure and calculate since it does not consider the diffraction quality of light, yet it tends to show higher values in the graph than actual images.
The readings at 10 lines per millimeter measure the lens's contrast ability ( red lines), repeating fine parallel lines spaced at 30 lines per millimeter measure the lens's sharpness ability (green lines), when the aperture is wide open.
Fine repeating line sets are created parallel to a diagonal line running from corner to corner of the frame, are called Sagittal lines (S) and sets of repeating lines vertical to these lines are drawn, called Moridional (M) line sets.
*The MTF chart gives the result at the wide-open aperture.
