The Leica M Typ 240 'Edition 100' is a special-edition digital rangefinder released as part of Leica's centenary celebrations marking 100 years of Leica photography. Built around the M Typ 240 platform, it uses the M-bayonet mount and was sold as a limited collector's set rather than as a standard production model.

Sales data for this edition is extremely thin: a single UK auction-hammer result on record stands at £2,000 (June 2020), so there is no meaningful range or median to draw on as of today. Buyers researching what an 'Edition 100' is worth in 2026 should treat that figure as one wholesale-level data point at saleroom level rather than a settled market price, since limited-edition Leicas are highly sensitive to set completeness, packaging and condition.
