The FED 2 Prototype is a Soviet 35mm rangefinder camera produced as a pre-production example of the FED 2 line at the FED works in Kharkov. Prototypes precede the regular production runs that defined the FED 2 family from the mid-1950s onward, and surviving examples are rare collector items rather than user cameras.

Auction data for the FED 2 Prototype is extremely thin: a single UK hammer result of £6,000 is on record (November 2019), so there is no meaningful range or median to quote today. Because that figure is a wholesale saleroom result rather than a retail asking price, what a FED 2 Prototype is worth in 2026 depends heavily on provenance, completeness and how convincingly the prototype status can be documented — a comparable example could sell for considerably more or less.
