Product description
Discuss in the Third Party Lens Talk forum
Manufacturer description: The Sigma 20mm F1.8 EX DG Aspherical Macro is a standard wide-angle lens for full-frame and APS-C digital SLRs. Although not a new lens, it remains popular for its combination of good build quality, a usefully fast aperture of F1.8 and decent optics. You don't get Sigma's HSM ultrasonic-type autofocus motor but a clever manual/auto focus clutch gives quick access to manual focus if you need to fine-tune.
