What happened when you try the Auto Geometry correct on the Roki in Lightroom / Acr?

I use DxO Photolab 5 and Viewpoint 3 to correct the fisheye curvature, which should be similar to what you can do in lightroom and other software.

Since you asked, here are results of perspective correcting the Rokinon 8mm shot and cropping to the 9mm field of view, converting to JPG at 'full' pixel resolution. I cropped from the center of the frame to get the least amount of distortion, so the image will look shifted, but the field of view is the same. Then a shot taken with the 9mm Laowa, downsampled to the same 'resolution' so it can be compared.

Canon M6ii, Rokinon 8mm f2.8 fisheye at f5.6, distortion correction using DxO PL5 & Viewpoint 3 to 'rectilinear', field of view cropped (centered) to match that of 9mm Laowa lens

Canon M6ii, Laowa 9mm f2.8 lens at f4, downsampled to same size as Rokinon '9mm cropped' image

Here's a similar comparison of the Rokinon 8mm fisheye curvature-corrected and cropped to the field of view of the Canon EF-M 11-22mm lens at f11, compared with the Canon downsampled to the same image resolution:

Canon M6ii, Rokinon 8mm f2.8 fisheye at f5.6, distortion correction using DxO PL5 & Viewpoint 3 to 'rectilinear', field of view cropped (centered) to match that of 11mm Canon 11-22 lens at 11mm

Canon M6ii,Canon EF_M 11-22 lens at 11mm, f5.6, downsampled to same size as Rokinon '11mm cropped' image

The Laowa and Canon lenses are sharper in the corners, but interestingly the curvature-corrected and cropped Rokinon fisheye results are better than you might expect, almost holding their own.
