I’ve been experimenting with both Gopro and SLR with fisheye and have made some discoveries.
Under some conditions fisheye works great, that is when all that you want to model has similar distance from the camera. So if one part of what you making a model of is very close and another part is far away inside the FOV the result isn’t as nice. I think it’s because of the difference in resolution in the image
I tried making a model of a road with the SLR and a 180 degrees fisheye, had it three meters up on a boom. Next I’ll try a normal vide angle even though it means more images.
