The Jaeger LeCoultre Compass camera was designed by English inventor and Member of Parliament Noel Pemberton Billings. It was notably much smaller than comparable cameras of its day, but not prohibitively expensive: only £30 when the product was launched in 1937. But just around 4,000 units were sold, making it extremely rare today. These days, a Compass can fetch around $2000.
The Compass was hailed as a scientific approach to photographic technique, but just as easy to use as a clock. It was meant to be used with glass plates, but an attachment could be purchased that would make it possible to use 35mm roll film (without the customary cassettes). It came with a standard tripod and cable release, which understandably weren’t included in the camera’s body.
