Mikey Schaefer is no stranger to the great outdoors. As a professional photographer who specializes in shooting in some of the most extreme environments on earth, he tests his body - and his gear - to the limits. In this field test we're following Mikey on a sports lifestyle / editorial shoot  with Canon's EOS 5DS and 5DSR, near his home town in Oregon. Take a look at the video above to find out how the 5DS and 5DSR fare in the outdoors, and see a few still images from the shoot below.
