After seeing all the highly positive reviews, I decided on this Sigma fish-eye for my Nikon D750. When you need extremely wide, 180 degree field of view, this lens delivers wonderfully. I find its sharp wide open, and it performs surprisingly well in the corners, see included landscape image. Another great feature of this lens is its close focus distance of 5.9" that enables you to take some very creative images.
