The Ducati Sogno 'PER COLLABORATORE' is a 35mm subminiature camera produced in Italy in the late 1940s by the same Ducati industrial concern better known for motorcycles. The 'PER COLLABORATORE' marking denotes an example presented to a company collaborator rather than a standard retail issue, making it a presentation variant aimed at insiders rather than the general market.

With only one UK auction record on file, the Ducati Sogno 'PER COLLABORATORE' is too thinly traded to support a true median, but the single hammer result of £950 (November 2016) gives a working reference point for what one is worth at saleroom level. Today, anyone asking how much a Sogno 'PER COLLABORATORE' sells for should treat that figure as wholesale auction value rather than a dealer or retail price, with condition, completeness of accessories and clarity of the presentation engraving the main factors in whether a future example trades above or below it.
