Sigma 10-20mm f/3.5 EX DC HSM
Improved quality and a reduced price give this lens the edge
Wide-angle zoom lens > £399, $650 > www.sigmaphoto.com Constant aperture ultra-wide lenses usually command big bucks, but recent price drops (in the UK at least) have made this lens tempting. Combine that with the standout sharpness and colour fringing performance of our most recent review sample and it’s a bargain.
Distortion levels are also impressive, with well-controlled barrel distortion at maximum wide angle that’s eliminated at mid-zoom. By 20mm there’s only a hint of pincushion distortion.
Factor in the benefits of that constant f/3.5 aperture and you’ve got a near-faultless winner.
Upgrade if you own... a standard 18-55mm or 18-135mm Nikon DX-fit kit lens and want to go much wider without compromising on quality.
runner up... Sigma 10-20mm f/4-5.6 EX DC HSM
Almost a decade old but still going strong, Sigma’s classic ultra-wide is now quite a bargain. It’ll worry far pricier lenses with its respectable sharpness and distortion levels.
