The Alpa 11es 'Jubilé 50' is a 35mm SLR produced by Pignons SA of Ballaigues, Switzerland, issued to mark the 50th anniversary of the Alpa line. It belongs to the final generation of Alpa reflex cameras and was made in very limited numbers, positioning it at the top of the range when new.

With only one tracked UK auction result, the 'Jubilé 50' is exceptionally thinly traded: a single hammer price of £8,000 was recorded in June 2025, and that figure is the only saleroom evidence of what the camera is worth today in 2026. Because this is a wholesale auction result rather than a retail asking price, dealer-listed examples typically sell for more, and value is highly sensitive to completeness of the commemorative presentation set and cosmetic condition.
