The Canon F-1 'U.S. NAVY' is a service-marked variant of the Canon F-1, a 35mm professional SLR using the Canon FD lens mount. The standard F-1 line was introduced in 1971 as Canon's flagship system camera; the 'U.S. NAVY' designation refers to examples issued to or marked for U.S. Navy service use.

Auction data for this specific service-marked variant is extremely thin, with only a single recorded hammer result of £700 at UK auction in 2012. Because that figure reflects one wholesale saleroom result from over a decade ago, it is not a reliable guide to what a 'U.S. NAVY' F-1 would sell for today, and condition, completeness of markings, and provenance documentation drive value far more than the base F-1 price. Buyers researching what a Canon F-1 'U.S. NAVY' is worth should treat the available figure as indicative only.
