After looking at the Nikon AF-D series, DxOMark continues working its way through the history of photography by presenting the measurements for another “antique” lens, the Canon EF 20-35mm f/3.5-4.5 USM. |
 |
DxOMark continues its exploration of the past with this very good wide-angle lens that Sigma first produced for Canon mounts in 2003, and while we’re at it, we’ll use this opportunity to compare it with one of the most best-known lenses on the market, the Canon EF 16-35mm f/2.8L II USM. |
 |
Very wide-angle lenses allow photographers to produce an image composed of a large number of objects and to frame very large subjects (such as buildings) at close proximity, and to photograph objects on different geometrical planes that can be very far apart. Such lenses also accentuate perspective, with the most noticeable result being the distortion of straight lines. |
