Leica Noctilux-M 50mm f/0.95 ASPH.

The fastest lens Leica has ever sold for the M system, the Noctilux-M 50mm f/0.95 ASPH. replaced the long-running f/1.0 Noctilux and pushed maximum aperture past the f/1.2 of the original 1966 design. Introduced in 2008, it arrived as Leica's most expensive M-mount lens and stayed that way for about a decade, becoming a signature object as much as a working tool [1][2]. Its reputation rests on the combination of an extreme f/0.95 aperture in a compact rangefinder body, something that had no real rival at launch and made the lens a status piece among collectors and available-light photographers.

Optically the lens uses an 8-element, 5-group design with two aspherical surfaces and a floating-element group that shifts during focusing to maintain correction across the focus range, a feature Leica markets with the FLE designation. The aperture is built from nine blades, and the barrel carries a 60mm (E60) filter thread with a built-in retractable hood. It is fully rangefinder coupled, focuses to a minimum distance of 1 m, and is finished to Leica's usual all-metal standard, which contributes to a substantial weight for a 50mm lens. Reviewers consistently praise the build quality and handling, though the size, the 1 m close-focus limit, and the weight are noted as practical trade-offs of the fast optic.

The standard production lens is offered in black anodized finish (model 11602), with a silver chrome version also catalogued (model 11667), and additional model numbers exist within the line (11612). Beyond the regular versions, Leica and its partners have produced limited runs, including a "Leica Shop Vienna" silver chrome limited edition of 50 pieces from 2010 (item 11698) and an f/0.95 Noctilux supplied as part of the Hermès-branded Leica M9 set in 2012. The lens carries a six-bit code (110001) for lens recognition on digital M bodies, applied in the bayonet rather than as the painted external coding used on some earlier lenses.

Optical qualities

Rendering The Noctilux f/0.95 is known for a distinctive look wide open: a thin plane of focus with a sharp, relatively high-contrast subject set against strongly blurred surroundings, the effect that drives most of its appeal as a portrait and low-light lens. Stopped down a little it gains high contrast and resolution and shows low distortion, while wide open it shows the field curvature, optical vignetting, and softer edges typical of an extreme-aperture design.

Bokeh and transitions Out-of-focus rendering is the lens's defining trait. In testing the background blur is smooth in the central region, but field curvature and optical vignetting can disturb the rendering toward the edges and corners at the widest apertures, which is the most common criticism leveled at it as a dedicated bokeh lens.

Aberrations Lateral chromatic aberration is described as almost absent, an achievement for the design era when such corrections had to be optical rather than software-based. Longitudinal chromatic aberration and coma are present wide open, consistent with the limits of f/0.95 lenses, with coma in particular cited as a weaker point.

Distortion and vignetting Distortion is low, while light falloff is significant at f/0.95 and improves on stopping down, again as expected for the maximum aperture.

Flare resistance Flare resistance is rated as average, with some ghosting and veiling flare visible against bright light sources.

History

Development and Launch Leica introduced the Noctilux-M 50mm f/0.95 ASPH. in 2008 as the successor to the f/1.0 Noctilux that had been in the catalogue since 1976. Its arrival coincided with a broader run of ambitious high-speed M lenses from Leica, and it represented the third distinct 50mm to carry the Noctilux name, after the 1966 f/1.2 and the long-lived f/1.0. Where the original f/1.2 used hand-ground aspherical surfaces, the f/0.95 combined modern aspherics with a floating element group to reach a faster aperture while controlling aberrations.

Special editions Documented limited and special versions include a silver chrome limited edition associated with Leica Shop Vienna, produced in a run of 50 pieces in 2010 under item number 11698, and an f/0.95 Noctilux supplied with the Hermès edition Leica M9 set in 2012. The regular silver chrome catalogue version (11667) is distinct from these limited runs.

Collector Notes Buyers should confirm which finish and model number a given example carries, since the black (11602) and silver (11667) catalogue versions and the rarer limited editions command different values. The built-in retractable hood and E60 filter thread are worth checking, along with the bayonet six-bit coding for correct recognition on digital M cameras. Because the lens is heavy and front-element accessories are specific to the 60mm thread, original caps, filters, and packaging add to collector desirability. Note that Leica's official data lists the weight as approximately 700 g, while at least one reviewer measured a higher figure without caps; the value recorded here follows the manufacturer's specification.
