The Rheinmetall Exa System is a 35mm SLR sold under the Rheinmetall brand, based on the East German Exa line that originated in Dresden in the 1950s. It was positioned as a simplified, lower-cost alternative to the contemporary Exakta, aimed at amateurs who wanted interchangeable-lens reflex photography without the price of a full system camera.

At UK auction the Rheinmetall Exa System has changed hands at hammer prices between roughly £69 and £110, with the two recorded results sitting either side of a £90 midpoint. The sample is small, so what a Rheinmetall Exa System sells for today depends heavily on cosmetic condition and whether a working lens is included; clean, functional examples tend to anchor the upper end of that range at saleroom level.
