The Sigma Canon EF 35mm f/1.4 DG HSM Art Lens is an optically advanced wide-angle prime lens with a fast design. Its bright f/1.4 maximum aperture allows for shallow depth of field and selective focus effects, making it suitable for challenging lighting conditions. The optical layout incorporates low dispersion and aspherical elements, which effectively control spherical and chromatic aberrations to enhance sharpness and clarity. A floating elements system ensures consistent performance throughout the focusing range. The lens features a Super Multi-Layer Coating that minimizes flare and ghosting, resulting in improved contrast and color accuracy, particularly in strong lighting conditions. In terms of autofocus performance, the lens is equipped with a Hyper Sonic Motor (HSM) that delivers quick, smooth, and quiet autofocus with full-time manual focus override. The physical design includes a brass bayonet mount for rigidity and mounting precision, as well as a seal to protect against dust and moisture. The rounded nine-blade diaphragm contributes to a pleasing bokeh quality. As part of Sigma’s Art line in the Global Vision series, this lens is designed to achieve outstanding optical performance and is ideal for creative and artistic applications. It is compatible with full-frame Canon EF-mount cameras and can also be used with APS-C models, providing a 56mm equivalent focal length.
