Leica 75mm f/1.25 Noctilux-M Asph. M-Mount Lens with Tripod Adapter, Built-In Lens Hood, Black, 6-Bit {E67} 11676

Leica Noctilux-M 75mm f/1.25 ASPH: the world's fastest aspherical 75mm.

Nine elements across six groups, built entirely from anomalous partial dispersion glass and low chromatic dispersion glass, every piece of this optical formula is selected to suppress color fringing before it starts. Two aspherical elements carry the sharpness load across the full image circle, and a floating rear element keeps that sharpness honest from the 85cm minimum focus distance all the way to infinity. At f/1.25, depth of field doesn't just get shallow; it gets surgical.

The 11-blade diaphragm earns its place here. Rounded bokeh at portrait distances is a direct consequence of that blade count, not a marketing claim. The built-in lens hood removes one variable from your kit bag, and 6-bit coding means compatible Leica M bodies read the lens automatically for exposure and correction data. At 1055g, this is a lens you'll feel, but the weight is the price of the glass formula inside.

Native to Leica M rangefinders, it also adapts to Sony E, Nikon Z, Canon RF, and L-Mount bodies, so the optical investment travels across systems. For portrait and available-light work, there is no aspherical 75mm faster on the market.

Who It's For

Portrait photographers working in ambient light will find the f/1.25 aperture does what studio flash cannot: it renders a subject in context while dissolving the surroundings into tone than texture. Documentary and editorial shooters who refuse strobes in sensitive environments get a 75mm that pulls usable images in low-light situations where slower glass fails. Leica M system shooters building a portrait-length complement to the 50mm Noctilux have the obvious pairing here. Mirrorless photographers on Sony E, Nikon Z, or L-Mount systems who want M-glass rendering with their existing bodies can adapt this lens without optical compromise.

FAQ

Is this lens faster than the Leica Noctilux-M 50mm f/0.95?

No. The 50mm f/0.95 is faster by one stop, but the 75mm f/1.25 is the fastest aspherical 75mm lens on the market - nothing matches it at that focal length and aperture combination.

What's the minimum focus distance?

85 centimeters (2.8 feet). The floating rear element maintains sharpness from that distance through infinity without focus breathing.

Does this lens adapt to mirrorless cameras?

Yes. It's native to Leica M rangefinders but adapts to Sony E, Nikon Z, Canon RF, and L-Mount systems. You'll need a third-party adapter for mirrorless bodies.

Why does the optical formula use anomalous partial dispersion glass?

It suppresses color fringing before it starts. Every element was selected specifically to control chromatic aberration, which matters at f/1.25 where residual fringing becomes visible fast.

How much depth of field do you get at f/1.25?

At portrait distance (roughly 1.5 meters), depth of field is less than 2 centimeters. That's surgical isolation - subject separation is extreme.

What's included in the box?

Metal lens cap, clip-on lens cap, rear lens cap, built-in lens hood, tripod adapter, and soft nappa leather cases for both the lens and tripod adapter.

How much does it weigh?

1055 grams (2.3 pounds). It's substantial, but the weight comes from the glass formula - you're carrying optical quality, not ballast.
