This large aperture, wideangle zoom for full-frame mirrorless cameras provides excellent quality at a very competitive price. It’s available in both Sony E-mount, and L-mount for Leica, Panasonic and Sigma cameras. By optimising the design for mirrorless, Sigma has made a lens that’s considerably smaller and lighter than its DSLR counterpart, yet provides fantastic optical quality. It also boasts fast and silent autofocus, and is weather-sealed for outdoor shooting. The result is a superb lens that’s perfect for a wide range of subjects including architecture, landscapes and astrophotography.
