The Zeiss Ikon Ideal 225 is a folding plate camera produced by Zeiss Ikon in the early 20th century. It was offered as a higher-tier folding camera in its day, aimed at photographers who wanted a precision-built pocketable plate camera.

Auction data for the Ideal 225 is thin: a single UK saleroom hammer result on file from 2003 fetched £104, which gives only a historical wholesale reference point rather than a current market price. With one data point, it is not possible to quote a reliable median or range for what an Ideal 225 sells for today, and condition, completeness of the original case, and working shutter will all materially affect value.
