The Goerz Roll-Tenax (also catalogued as Rollfilm-Tenax) in the 6.5x11 cm format is an early 20th-century rollfilm folding camera produced by the German optical maker C.P. Goerz. It was offered as a compact-folding alternative to the plate-back Tenax line, aimed at amateur photographers wanting a larger-than-postcard negative on rollfilm.

Sales data for the 6.5x11 Roll-Tenax is extremely thin: the only recorded UK auction hammer result is £115 from 2004, so there is no current median or range to cite for today's market. Because that figure is more than two decades old and represents a single saleroom result rather than a retail or dealer asking price, it should be treated as indicative only when judging what a comparable example might be worth in 2026.
