The Bentzin Primarflex II (Primar Reflex II) is a German medium-format 6×6 single-lens reflex camera using 120 roll film, produced by the Dresden maker Bentzin in the post-war period. It was a waist-level SLR positioned in the same broader category as other German 6×6 reflexes of its era.

With only two recorded UK auction hammer results on file (2005), the Primarflex II sold for £280 and £385, giving a midpoint around £330. Because the sample is small and dated, today's value is hard to pin down from this data alone, and what a Primarflex II is worth at saleroom level will depend heavily on cosmetic condition, shutter function, and whether a working lens is fitted.
