The Zeiss Ikon Ideal 250/3 is a folding plate camera produced by Zeiss Ikon in the early twentieth century. It belongs to the company's range of medium-format folding plate cameras aimed at advanced amateurs of its era.

Sales data for the Ideal 250/3 is very limited: a single UK auction hammer result from May 2025 saw an example sell for £62. With only one wholesale saleroom result on record, today's market value is best treated as indicative rather than firmly established, and condition, completeness of the lens/shutter assembly, and bellows integrity will heavily influence what any given example is worth.
