    Your Lr version is from a different original.

    Here's your posted "original" corrected in Lr5 using the Nikon AF-Fisheye 16mm f/2.8 correction profile along with some slight additional correction and the cropping necessary to remove empty areas at the center top and center bottom while maintaining the 4:3 aspect ratio. It could be slightly wider if I let the aspect ratio change. 11477336673_dc664e1bdb_c-edit.

    I went to Flickr to see if there were larger versions of these pics for better viewing but it says they're private...

    If you share the original, I can run a few comparisons via hugin (freeware) which is what I use for samyang defish

    There are user profiles available for the Samyang 7.5 mm:

    I think they are better than using Sigma 8 mm.
    The best thing is that you can use other projections than rectilinear: stereographic is very very interesting.

    In fact, the stereographic projetction is the reason I like my Samyang 7.5 mm so much.
