The Pathé Frères Professional Reflex 16AT BTL is a 16mm motion picture camera from the French manufacturer Pathé Frères, a company with roots in early French cinema equipment. It is a professional reflex cine camera rather than a still camera, aimed at the working filmmaker market.

Auction data for this model is extremely thin: a single UK saleroom hammer result from 2001 records a price of £188, which gives only a historic reference point rather than a current market value. With no recent comparable sales, what a Pathé Frères Professional Reflex 16AT BTL is worth or sells for today cannot be reliably stated, and any 2026 valuation would need fresh auction evidence to confirm a price range.
