The Sigma 35mm F1.2 DG II | Art offers even better optical performance than its predecessor, with brilliant clarity throughout the image, even at the fully open F1.2 aperture. The use of SLD glass, highly refractive glass with high anomalous dispersion, and four glass moulded double-sided aspherical elements thoroughly corrects axial chromatic aberration and sagittal coma flare, while significantly reducing the lens size.

Optimisation of the focus group arrangement and aspherical shape significantly suppresses focus breathing. As a result, changes in field of view are effectively suppressed when the focusing distance is changed, making the lens an ideal choice for professional video use. High backlight resistance enables clear and sharp images under any lighting conditions.

The Sigma 35mm F1.2 DG II | Art achieves even better optical performance than its predecessor while being approximately 30% lighter and 20% shorter. A key factor behind this is the adoption of a floating focus design: by allowing the lens groups to move independently of each other, the weight of each lens group has been significantly reduced while simultaneously enhancing optical performance. Additionally, the improved optical design features four aspherical lens elements, high refractive index glass, and thinner lens elements, further contributing to its exceptional performance.

The lens features an AFL button that can be assigned a variety of functions on compatible cameras. In addition, the aperture ring can be locked with the dedicated lock switch and changed from clicked to de-clicked with the dedicated click switch.

In addition to a dust & splash-resistant structure, the front element of the lens features a water & oil-repellent coating, allowing photographers to shoot without concerns even in harsh outdoor environments.
