The Leitz 75mm f/1.25 Noctilux-M ASPH is an ultra-fast aspherical short telephoto for the Leica M rangefinder bayonet mount. Released in the modern era as a successor to the legendary 50mm Noctilux concept at a longer focal length, it is designed for available-light shooting and razor-thin depth-of-field portraiture, and is widely regarded as the flagship of the current M-system lens line.

Auction data for the 75mm f/1.25 Noctilux-M ASPH is extremely thin: the only verified UK saleroom record we hold is a single hammer result of £17,000 from June 2021, which gives both the high and low of the recorded range. Because that figure is a wholesale auction-hammer price rather than a dealer asking price, retail value in 2026 sits noticeably above that level, and clean, boxed copies tend to fetch a meaningful premium when they do appear. With only one data point, today's market price is best treated as indicative rather than a firm median.
