Its f/1.4 aperture and 15-element optical design with 3 aspherical and 1 ED element deliver sharp, high-contrast images with minimal aberrations, even wide open. The weather-sealed, 370g build and fast linear motor autofocus make it a durable, responsive tool for any environment. This 27mm-equivalent prime is best for documentary and street photographers who need a rugged, wide-angle lens that excels in low light.
