The Leitz M-A 'Edition 100' (pre-series) is a 35mm mechanical rangefinder camera released as part of Leitz's 100-year anniversary commemoration. Pre-series examples were produced ahead of the standard run and are scarce on the open market, which places them in collector territory rather than user-camera territory when considering price and value today.

Auction data for this pre-series variant is extremely thin: a single UK saleroom hammer result of £16,000 in June 2021 is the only reference point, so any sense of what one is worth in 2026 rests on that lone data point. Because this was a UK auction hammer figure — wholesale level, before buyer's premium — the price an end buyer actually pays at retail or via a specialist dealer would sit meaningfully higher. With only one comparable, condition, completeness of presentation set, and serial-number desirability will swing where the next example sells for far more than the headline number suggests.
