I dont understand how defish uses fov parameter. It cant be both the angle and control distortion...
It is, because the input and output projections are assumed to be fisheye and rectilinear.

Having vaguely followed this rather meandering thread, I feel it's worth pointing out again that if the aim is to find a projection where 3D rotation can be eliminated by changing the projection, translating the image in 2D, and then changing the projection back, then no such projection exists.
