Sigma 10-20mm f/3.5 EX DC HSM lens review with samples

This is one of Sigma’s ’flagship’ lenses - an ultra wide-angle lens for APS-C cameras, with a snappy maximum aperture of f/3.5 throughout its entire zoom range. That means it could be quite flexible for low-light shooting and video work. But does it have the optics to match up to its ambitious design? All pictures and footage shot by me on a Canon 70D camera. Music: ’Opportunity Walks’, Kevin MacLeod () Licensed under Creative Commons: By Attribution 3.0
