The Zeiss Ikon Cocarette Luxus I 521/2 is a folding rollfilm camera produced by Zeiss Ikon, the German manufacturer formed in 1926. The Luxus designation indicates a deluxe variant of the Cocarette folder line.

With only a single recorded UK auction hammer result for this model, market evidence is thin: one example sold for £183 in 2003, which remains the only data point available as of 2026. Because saleroom appearances are rare, today's value, price, and what a clean example sells for would depend heavily on cosmetic condition, completeness of the leather covering, and shutter function.
