Built on Sigma’s latest optical design technology, the Art 35mm f1.4 DG II has been completely redesigned with 15-element, 12-group construction that 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 colour bleeding
By thoroughly correcting axial chromatic aberration, the lens suppresses colour 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 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—the Sigma 35mm F1.4 DG DN | Art—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 users can capture decisive moments reliably.
