Remember with a AF wide angle lens, you still can set it to do MF. As true wide angle is more useful then a fish eye. Especially if you do not want to do to much pp editing to correct for defishing. I have had fish eyes in the past, and I rather have a pure wide angle over a fish eye for the every day uses, as I get more uses out of WA then a fish eye.
