Here is a a close-up view of Upper Yosemite Fall taken with a Canon EOS 7D MKII using a 100-400mm zoom lens.  I took this photograph on the Yosemite Falls trail last week while visiting Yosemite.  I had the lens set at 400mm and took a lot of pictures of the water flowing down the mountain side.  I ended up taking a few hundred pictures between 100mm and 400mm and all the pictures looked different because of the flow of the water and the wind blowing the water.  It was a very fascinating experience seeing the water moving and constantly changing.
