The Goerz Tenax, often referred to as the Baby Tenax, is a small-format folding plate camera produced in the early twentieth century by the German optical maker C.P. Goerz. It was positioned as a compact, pocketable instrument for amateur photographers seeking a higher-quality alternative to box cameras of the period.

With only a single recent UK auction record to draw on, the Tenax (Baby Tenax) sells for modest sums at saleroom level: a hammer price of £38 was achieved in October 2025. Today the worth of any individual example will depend heavily on cosmetic condition, completeness of the original lens and shutter, and whether the bellows remain light-tight, so the wholesale value of a clean example could deviate noticeably from this single data point.
