The camera used to make these photos was the Vivitar Ultra Wide & Slim. I got my first one on ebay for $10. The next two cost 99 cents each at a local thrift store. The price of the camera soared when production was stopped for a time. Even though production has now resumed, people are still paying $30 to $40 for the camera. The construction of the camera is pretty flimsy, though it is light-tight. The 22mm lens is extraordinary, being a two element design that is very sharp, with little distortion for an ultra wide-angle.
