Live view is invaluable for focusing on the face of this bison in heavy snowfall in Yellowstone. The autofocus continually jumps back and forth as it "sees" the falling snow, and seldom focuses on the bison. Here I use manual focus with live view, magnify the bison's face by 10x in the live image, manually focus on the hair between the small horns, and shoot away with sharp focus. Canon USA asked me to review the new Canon 6D Mark II during the summer of 2017. Always one to try a new camera,
