As an avid photographer, I was looking for a lens that could handle whatever nature threw its way... with this lens, I found it. It’s freeze resistant AND great for braving the elements. The image quality is out of this world and the auto-focusing is incredibly accurate. As a result of my tests, i determined that this lens is a superb addition to my photography kit. Make sure you note that this lens comes at a high price point, but for me, the results were worth the investment..
