The Lorenz Clarissa Tropen (Tropical) is a tropical-finish folding plate camera, a body style produced for use in hot and humid climates with brass fittings and wood or leather covering in place of standard finishes. It belongs to the early 20th-century European folding-camera tradition, where Tropen variants were sold at a premium over the standard models.

Auction evidence for this model is extremely thin: a single Christie's hammer result from November 2002 sold for £998. With only one UK auction-hammer datapoint on record, today's value cannot be reliably triangulated, and any current price estimate would be speculative; collectors should treat that 2002 figure as a historical reference rather than a guide to what the camera is worth or sells for in 2026.
