The Orionwerk Tropen Rio 5 C is a tropical-bodied folding plate camera made in Germany by Orionwerk. Tropical models of this era were finished with teak or similar hardwoods and brass fittings, intended for use in hot, humid climates where standard leatherette-covered bodies degraded.

Sales data for this model is extremely thin: a single recorded UK auction hammer result of £320 in 2008, which sits at wholesale saleroom level rather than retail. With only one data point on file, that figure is indicative rather than a reliable guide to what a Tropen Rio 5 C is worth today, and condition of the wood, bellows and brightwork would heavily influence any current price or value achieved at auction.
