The Minolta Riva Panoramic aka Minolta P's is a 35mm film camera with a special features: It takes only panoramic photos. Panoramic - not panorama. So it literally cuts from the top and the botton of the frame in order to achieve a panoramic effect.
Sometimes it is considered to be the poornman's XPAN referring to the fantastic Hasselblad XPAN (aka Fuji TX-2). The Hasselblad was actually build by Fuji and is identical to Fujis TX-2. The special feature of these cameras is that they actually do take panorma photos. Both are 35mm film cameras. Whenever you take a photo, two frames are exposed - thus, creating an actual panorama photo.
Two fanatastic camera's with a fantastical price - somewhere around 2500 - 3500 EUR. I like my small Minolta though - it was 68 EUR
