The Canon F-1N "50th Anniversary" is a commemorative variant of Canon's professional 35mm SLR system, released to mark the company's 50 years in business. It uses the Canon FD manual-focus lens mount and was sold in limited numbers, which is the main driver of its collector value today.

Auction data for this commemorative variant is thin: a single UK saleroom result from 2019 saw an example sell for £1,300 at hammer (wholesale, before commission). With only one verified data point, today's value is best treated as indicative rather than a firm guide, and clean, boxed examples with original paperwork are what command this kind of price.
