Digital Camera World Verdict

20mm f/1.8 lenses are relatively common but this Sigma goes two-thirds of an f/stop faster at f/1.4, becoming a world-first for full-frame cameras. The extra light-gathering potential is great for shooting landscapes at twilight, architectural interiors and the night sky. With impressive build quality, image quality and overall performance, and considering the technical challenge of making a 20mm f/1.4 lens, the Sigma is excellent value at the price.

  • +

    Very good value for money

Cons

When you need an ultra-wide viewing angle with a fast aperture, the Sigma 20mm f/1.4 DG HSM Art fits the bill perfectly. Originally designed for Canon EF and Nikon F mount DSLRs, it’s been subsequently adapted to also include Leica L and Sony E mount options, thus making it available for mirrorless cameras as well. That said, there’s a more recent and completely redesigned ‘DG DN’ version for mirrorless cameras in these two mount options, which delivers even better performance.
