All panoramas on this site have been shoot during the development of the PanoBot and the GigaPanBot.

I'm using the Olympus E-520 with 8mm Zuiko lens for 'normal' spherical panoramas. For higher resolution panoramas i also use the 12-60mm Zuiko lens as well as the 70-300mm lens for the gigapixel panoramas.
Most of the panoramas shown on this site are also hosted at 360cities. 360cities offers a great interface at high resolution.
