The Sigma AF 35mm f1.4 ART is an optically advanced wide-angle prime lens that brings impressive creative control to your Canon EF-mount camera. Built around a fast f/1.4 maximum aperture, this lens delivers shallow depth of field and excellent low-light performance. The optical design features 13 elements in 11 groups, including two aspherical elements and four Special Low Dispersion (SLD) elements that work together to minimise chromatic aberration and field curvature. A Super Multi-Layer Coating reduces flare and ghosting for sharp, high-contrast images even in challenging lighting. The integrated Hyper Sonic Motor (HSM) provides quick and quiet autofocusing with full-time manual focus override, whilst the brass bayonet mount with rubber sealing offers durability and dust/splash resistance. Perfect for portraiture, street photography, and environmental work, this secondhand lens remains a highly respected choice among Canon users.
