Ok, so maybe not the most "alt" stuff out there, but whatever. The Tokina lens I have is probably one in a billion! It is so sharp (atleast I keep telling myself that, lol) and the specific Tokina lens I have is the 17mm 3.5 R.M.C. in Nikon mount and I use it with my 1Ds. Pretty alt I guess.
I will start this off with an image. If there is an image thread, I apologize.
