This camera mount from Novoflex is designed to work with certain fisheye lenses to make spherical panoramic photography a snap. The VR-System SLANT mount holds the camera at an angle that makes it possible to get a complete spherical panorama for internet applications like virtual tours with only 3 or 4 overlapping exposures. It works especially well with a monopod. The VR-System SLANT is € 249 (about $360) at Novoflex online. Check the mount information page to be sure it will work with your equipment.
