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

£1269/$1299 A formidable Sigma trinity zoom

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

The weather-sealed construction is excellent. Optical prowess benefits from a large-diameter, ultra-highprecision 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.

Performance

Levels of sharpness are ace across the whole image and throughout the entire zoom range. 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 landscape shooting.

N-photo verdict

Pro-grade build quality and stellar image quality make this a stunning full-frame landscape lens.

Sharpness

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

Fringing

Levels of colour fringing are absolutely negligible, even when it comes to the extreme corners of the frame.

Distortion

Close-up lab-results don’t look inspiring but in landscape shooting, it’s effectively a zero-distortion lens.
