Leica 50MM (1961–2004)
At 301 grams, it balances like a promise on an M3—fast glass that defined a generation of street photography.
Overview
The Leica SUMMILUX 50mm f/1.4 isn’t just a lens—it’s a declaration. Introduced in 1961 as a standard ultrahigh-speed normal lens for the M-mount system, it offered Leica shooters unprecedented low-light capability with a wide f/1.4 aperture. Built for the chrome-domed M3s and M2s of the era, it quickly became a favorite among photojournalists who needed speed, contrast, and a certain bite in their images. While later iterations would refine coatings and tolerances, the core optical formula remained consistent across its remarkable 43-year production span, which stretched from 1961 to 2004 according to Ken Rockwell.
Alongside it, the Leica SUMMICRON-M 50mm f/2 emerged in 1979 as a more compact, slightly slower alternative—renowned for its micro-contrast and rendering, with a current cosmetic version in production since 1994. More recently, the APO-Summicron-M 50mm f/2 ASPH. (Type 6) has joined the lineup, representing the modern pinnacle of Leica’s 50mm engineering, though specific production dates and pricing remain undocumented in available sources. While the Summilux drew attention for its speed and presence, the Summicron earned loyalty through consistency and balance—two philosophies embodied in glass and steel.

Key Features
Traditional Non-Aspherical Optical Design with Cemented Elements
The SUMMILUX 50mm f/1.4 relies on a spherical optical formula that avoids aspherical elements, a hallmark of its era. Its design features cemented second and third elements, while the sixth and seventh remain separate—a configuration that contributes to its distinctive rendering, especially wide open. This layout, consistent in the 1961 and later versions, delivers a complex bokeh with a slight swirl in the outer zones, a trait many photographers describe as organic or even “alive.” While not corrected to the clinical standards of modern lenses, its imperfections are part of its appeal—images exhibit micro-contrast and a three-dimensional pop that digital post-processing often fails to replicate.
Consistent Coatings Across Four Decades
Despite evolving manufacturing techniques, Leica maintained identical coatings on the SUMMILUX 50mm f/1.4 throughout its entire production run from 1961 to 2004. This uniformity means that optical performance—particularly flare resistance and color transmission—remains remarkably consistent across generations. Flare is present when shooting into strong light, but it tends to manifest as soft veiling rather than harsh streaks, a characteristic some find poetic rather than problematic.
43mm Filter Thread Across Early and Chrome Versions
Both the early (1959–1961) and chrome (1961–1968) versions of the SUMMILUX 50mm f/1.4 share a 43mm filter thread, a size that was common in Leica’s lineup at the time. This allows for compatibility with a wide range of period-correct filters, including UV, yellow, and polarizers.
Historical Context
The SUMMILUX 50mm f/1.4 debuted in 1961 as Leica’s answer to the growing demand for faster standard lenses in photojournalism and low-light candid photography. The M-mount chrome version was produced until 1968, The SUMMICRON-M 50mm f/2 followed in 1979, offering a more compact and consistently manufactured alternative, with its current cosmetic iteration dating from 1994. The APO-Summicron-M 50mm f/2 ASPH. (Type 6) represents the latest evolution, though production details remain unconfirmed.
Collectibility & Value
The original used price for the chrome SUMMILUX 50mm f/1.4 (1961–1968) was approximately $2,270, according to Ken Rockwell’s documentation. By comparison, the 1994–2013 version of the SUMMICRON-M 50mm f/2 carried a new price of around $2,000 and a used value of about $1,100. The 2025 re-edition of the SUMMILUX 50mm f/1.4 is priced at $3,895, reflecting both brand prestige and material costs. No documented failure modes or common defects are cited in available sources.
