The Rietzschel Ninon Tropical is a tropical-pattern plate camera, a body type produced for use in hot and humid climates and typically distinguished by exposed brass or teak construction in place of standard leather covering. As a tropical model it sits at the upper end of Rietzschel's pre-war plate camera output.

Sales data for the Ninon Tropical is extremely thin: a single UK auction hammer record from 2012 shows a price of £400, which gives an indicative value rather than a reliable market median. With only one data point, today's worth depends heavily on condition, completeness of lens and shutter, and bidder competition on the day, so prices realised at saleroom level can swing well above or below this figure.
