The combination of Zenitar 16mm fish eye lens and Sony alpha7R 36 Mpix fullframe camera takes 200 megapixel spherical panoramas -- about the resolution of the unaided human eye.  This is a test of the shooting pattern I expect to use with a hand-supported pole: 1 up, 6 around level, 2 down with the pole extended slightly and slanted in opposite directions, camera above nadir as close as I can judge by eye.  ISO 800, f/8, 1/10 sec, camera jpeg at 'standard' compression, stitched to exactly 200 Mpix equirectanglular with PTGui.
