This is a good example of what happens when you try to go too wide with a rectilinear lens. You end up with what I call corner stretching. Full frame fisheyes resolve this by allowing curvilinear distortion. Personally, I prefer the full frame fisheye with its curvilinear distortion to the corner stretching visible with this lens. And the full frame fisheyes cover 180 degrees across the bias. It is an interesting technology, however. Thanks for the post.
