The quest to make a ridiculously small, yet still fully-featured camera is not a new one. For historical examples, look no further than the Compass Camera. Made by Swiss watchmaker LeCoultre, it was designed by Englishman Noel Pemberton Billing and sold by Compass Cameras of London starting in 1937. It features a collapsible design and accepts 24x36mm plate film (a roll film back was later introduced).

Take a look at the video above for a full tour of the camera. Only around 5000 were produced, and they're now highly sought after by collectors. In fact, you can pick one up now on ebay if you have $7450 to spare.
