Most fisheye lenses have lens profiles for Lightroom that can defish. I use the Samyang 7.5mm fisheye for micro four-thirds, and the lens profile not only lens corrects, but can also remap to equal area, equidistant, rectilinear, and stereographic. If you can't find one specific to your lens, using a similar fisheye profile can also work.
