Yep. 16mm fisheye on a Sony A900. I shot it in aperture mode with the lens stopped right down to give slowish shutter speeds.
The camera was fixed to the car by drilling a 1/4" hole through the roof rack top rail and then screwing on a ball head mount from my monopod (if you look closely, you can see the shadow of it.). I also used a remote shutter release but the lead wasn't quite long enough so I gaffer-taped it to just above the driver's door. The camera was in continuous fire mode but I'd turn it off and on for traffic lights, etc. I still ended up with about 2.5GBs of pictures.
The things you do on a slow Sunday arvo. :)
