The Zeiss Ikon Deckrullo Nettel Tropen (Tropical) is a folding plate camera built with teak and brown leather for use in hot, humid climates. It dates from the early 20th century and used a focal-plane shutter, positioning it as a professional press and field camera of its era.

Auction data for this model is extremely thin: the only recorded UK saleroom result on file is a single hammer price of £400 from 2003, so a meaningful current range cannot be cited for today's market. With one wholesale data point more than two decades old, what a Deckrullo Nettel Tropen is worth now depends heavily on condition, completeness of the original lens and plate holders, and whether the teak and leather have survived without warping or shrinkage.
