The Fuji Instax Mini 7S takes credit card sized polaroid photographs and requires specialized film for this camera and it looks like it's only available in Japan?
The other is the Demekin Pocket Fisheye Camera which looks like a 1960s underwater device (It's not. Unless you put it in a water-tight casing). It costs Aussie$65 and also requires a film that is relatively obscure these days.
