The Kern Bijou is a Swiss-made plate camera produced by Kern, a manufacturer better known for its optics. As a small-format plate camera, it sits within the early 20th-century tradition of compact travel and field cameras.

At recent UK auction, hammer prices for the Kern Bijou have ranged from around £380 to £500, with only a small number of verified sales on record as of today. Because these are saleroom hammer results rather than retail prices, the value achieved depends heavily on condition, completeness of the original case and plate holders, and the state of the fitted Kern lens and shutter.
