The SIGMA 10-20mm F3.5 EX DC HSM for Outdoor Action Photography
Editor’s Note: This is an in-depth look at the SIGMA 10-20mm F3.5 EX DC HSM lens — which has since been discontinued — by now SIGMA Ambassador, Liam Doran.
For many photographers, their first camera is typically a crop sensor camera. This is because they are generally less expensive, and more compact than their full frame counterparts. Additionally most of these entry level or even mid level cameras come paired with a kit lens like an 18-55mm, 28-135mm, or even 24-105mm. And while this is a great place to start your lens collection you will soon notice that you are missing the “big picture.”
What I mean by this of course is the wide angle view for taking it all in. Enter the SIGMA 10-20mm F3.5 EX DC HSM. On a crop sensor camera like the Canon 7DMKII or Nikon D7200, the SIGMA 10-20mm F3.5 will convert to either a 16mm-33mm or 15mm-30mm, respectively. Unlike a fisheye lens, the 10-20mm F3.5 is rectilinear, meaning that it won’t distort straight lines while taking in very wide fields of view which is great for landscape, event and editorial photographers! Here’s a sampling of outdoor and adventure images made with this outstanding ultrawide!
