The Bolex B8SL is a 8mm cine camera from the Swiss maker Bolex, a brand long associated with small-gauge motion-picture equipment. It sits within the standard 8mm consumer-amateur movie camera segment of the mid-20th century.

Sales data for the B8SL is very thin: a single UK auction hammer result from January 2024 shows the camera selling for £44, which reflects wholesale saleroom levels rather than dealer retail pricing. On that limited evidence, today's value for a B8SL in average condition appears to be modest, well under £100, though one data point is not enough to establish a reliable price range.
