Leitz M Prototype (24x24)
The Leitz M Prototype (24x24) is a 35mm rangefinder body built around an experimental square 24×24mm frame format rather than the standard 24×36mm full frame used on production M cameras. It is a one-off or very-limited factory development piece rather than a catalogue model, which places it firmly in the collector-prototype category.
Sales evidence is extremely thin: a single recorded UK auction hammer result of £3,000 from 2009 stands as the only reference point, so any sense of what this prototype is worth today rests on that lone wholesale data point rather than a true range. Because saleroom appearances are so rare, the price a fresh example sells for in 2026 would be driven far more by provenance, documentation and bidder competition on the day than by any established median value.

Frequently asked questions
What is a Leitz M Prototype (24x24) worth?
The only recorded UK auction sale hammered at £3,000, but with just one data point the true value range is not reliably established.
How much does a Leitz M Prototype (24x24) sell for at auction?
On the single available reference, it sold for £3,000 at hammer, excluding buyer's premium; future results could vary widely with provenance.
Why is this prototype priced differently from a standard Leica M?
It uses an experimental 24×24mm square frame rather than the standard 24×36mm format, making it a development piece whose price is driven by rarity and provenance rather than user demand.
