Sigma 10-20mm F3.5 EX DC HSM for Outdoor Action Photography

1/800 sec. f8.0 ISO 400 at 10mm on Canon 7D with off camera flash.  From top to bottom and foreground to background there is a lot for the eye to see in this image.  That is the beauty of a wide angle like the 10-20 f3.5 EX DC HSM to put an athlete in an environment.

10-20mm f3.5 DC HSM: A must have lens for the outdoor sports shooter

©2013 Liam Doran | Sharp, light, fast and tough…the 10-20f3.5 makes it in the pack for multiday expeditions. Focal length: 10mm | Shutter speed: 1/800 sec | Aperture: F6.3 | ISO: 200

One of the benefits for outdoor sports shooters on APS-C sensors is the gain in reach with telephotos lenses. The negative of course is that now your wide angle 16mm is now not so wide at 25.6mm. Thankfully Sigma has a great wide-angle lens perfect for crop sensor shooters…the 10-20mm f3.5! I picked up this lens about a year ago and have shot outdoor sports and adventure travel with it extensively.
