Samyang 8mm = Rokinon, Pro-Optic, Walimex, Falcon, many more names.
see http://photonius.wikispaces.com/Fish-eye...+Stitching
It's a nice lens for the price.
Note, as explained in the link, distance marks on the focus ring may be off, there seems to be some big variation. Some unsharpness at f3.5 that users report may be due to wrong focus. At f5.6, f8 DOF is big enough to cover it up.
The focus ring can be adjusted.
