The Bentzin Primar Reflex is a German-made medium-format single-lens reflex camera dating from the pre-war era of plate and roll-film SLR design. It was sold as a professional-tier waist-level reflex aimed at studio and portrait photographers when new.

Sales data for the Primar Reflex is thin, so its value today is hard to pin down with precision: a single UK auction hammer result from July 2023 saw an example sell for £212, which is the only reference point currently on file. Because this is a wholesale saleroom figure rather than a dealer asking price, retail-ready examples in 2026 typically command more, and condition of the bellows, shutter and ground glass has an outsized effect on what the camera is worth.
