I am not sure if Rokinon is a good brand. I want a fisheye lens that does the full 180 degrees. I am not sure if all fisheye lens do the full 180 degrees, I am also not sure if 8mm is good. I am not sure how the numbers work, I do not know if the higher the number the better or the lower the umber the better.
