Jupiter F-21
The Jupiter F-21 is a Soviet-era 21mm subminiature spy camera designed for covert photography. It is best known for its compact form factor and clockwork-driven film advance, intended for concealed use rather than general photography.
Sales data is extremely limited: a single UK auction hammer result from June 2022 saw a Jupiter F-21 sell for £150, and that figure remains the only reliable wholesale reference point as of today in 2026. With just one record on file, it is difficult to define a true price range or median, and condition, completeness of accessories (cassettes, winder key, viewfinder) and originality will materially affect what any given example is worth at saleroom level.

Frequently asked questions
What is a Jupiter F-21 worth today?
On the available evidence, a Jupiter F-21 is worth around £150 at UK auction, based on a single 2022 hammer price; that figure is the only verified value reference and should be treated as indicative rather than a firm market price.
How much does a Jupiter F-21 sell for at auction?
The one recorded UK auction sale fetched £150 hammer, so comparable examples in similar condition could reasonably be expected to sell for a broadly similar price, though small samples mean individual results can vary widely.
Is the Jupiter F-21 a good value subminiature camera?
At roughly £150, the price reflects its scarcity and collector appeal as a Soviet covert camera rather than practical shooting value, and buyers should weigh that against the difficulty of sourcing film cassettes and servicing.
