Lomographic Fisheye Camera
The original name of this camera is fisheye lomography camera. It is the first 35mm compact camera with a very-wide-angle lens (fisheye-lens) in the world. It is manufactured for the Lomographical Society International in Vienna, and is available as fun-camera through normal photo shops. It's not only a toy camera, it's a good cheap test camera for anyone who does not know if he or she really needs a super-wide-angle-SLR-lens. It's the optimal fisheye lens for those who don't really need one. For its price its fixfocus lens does surprisingly well. For using the flash a cheap AA-battery will be needed.
