The Bolsey-Flex is a mid-20th-century camera produced by the American maker Bolsey Corp. It sits in the lower-priced end of the postwar consumer camera market and is generally collected today as a period curiosity rather than a working tool.

At UK auction the Bolsey-Flex is a low-value lot: the only hammer result on file, from August 2024, sells for £40, which sets the current reference point for what a Bolsey-Flex is worth today. With just one data point on record, the price a clean example fetches at saleroom level can move materially either side of that figure depending on cosmetic condition and whether the shutter still fires.
