Overview

The Sigma 28mm F1.4 Art (L-mount) delivers excellent sharpness and a versatile 28mm focal length suited for landscape, street, and environmental portraits. Its build is solid, weather-sealed, and splash/dust resistant, though it is large and heavy. Optical weaknesses include noticeable distortion and vignetting. Autofocus is fast and reliable, and manual focus is smooth. It best suits photographers prioritizing optical quality and durability over portability.
