Sox the cat prefers to keep his eye on at least two vectors at once. Here he’s at the intersection of the kitchen and the hallway. His field of view is captured by the Rokinon 8mm. It’s supposedly a fish-eye, but it really seems to be more a hybrid between fish-eye and an ultra wide angle. It does a good job of capturing a near 180-degree field of view on the Nikon D90 APS-C sensor.
