Sigma 14-24mm f/2.8 DG HSM | A

£1129/$1199 It’s the landscape lens to beat

e’ve long been fans of Sigma’s ultra-wide 12-24mm lens, with its extreme maximum viewing angle. The Mk II edition was very good and the latest ‘Art’ edition is even better, gaining a constant-aperture rating of f/4. This addition to the Art line-up is more modest in its ultra-wide coverage but an f-stop faster.

The weather-sealed construction is of excellent quality. Optical prowess benefits from a large-diameter, ultra-high-precision moulded glass aspherical front element, which teams up with three top-grade FLD (‘Fluorite’ Low Dispersion) elements and three SLD (Special Low Dispersion) elements. Ring-type ultrasonic AF is speedy and whisper-quiet.

WPerformance

Sharpness is excellent across the whole frame and across the entire zoom range, even when shooting wide-open at f/2.8. Colour fringing is negligible and, despite the Sigma having average scores for barrel distortion based on close-range test charts, it’s effectively a distortion-free lens in real-world shooting.

Sharpness

Sharpness is superb across the entire image frame, even when shooting wideopen at f/2.8.

Fringing Distortion

Lab-results don’t look great, but for landscapes, it’s almost a zero-distortion lens.

Levels of colour fringing are negligible, even at the extreme corners of the frame.
