Sigma holds its Art series lenses to a high standard, so our interest was piqued when the company's CEO Kazuto Yamaki described the 40mm F1.4 as a 'reference' lens for the entire Global Vision range. While we had a chance to shoot with a pre-production model at Photokina, we were eager to really put the 40mm to work when a full production lens rolled into the office. Take a look at how it performed.
