The Moment-Magazin-Camera Tenax is a magazine camera for 9x12 cm plates, made by Goerz of Berlin in about 1892. It is made from mahogany wood. The plate magazine is at the side of the camera, not at the back as is common with detective cameras, making the camera a rather bulky shape. It has an unidentified lens and a guillotine shutter. There are Watson finders and tripod bushes for vertical and horizontal orientation. The auctioneer's notes at Westlicht state that the patent for the camera was held by a Danish designer, Möller.
- Moment-Magazin-Camera Tenax sold at the sixth Westlicht Photographica Auction, on 6 November 2004.
- Swiss Patent 11648, Photographischer Apparat, filed 1895 and granted to B. Möller in 1896 (i.e. a few years after this camera) describes another detective camera, this time with the plates stored behind the camera, but end-on to the lens, the patent protecting the plate-changing mechanism.
