Voigtlander Nokton 35mm f/1.2 Aspherical (VM)

Two-thirds of a stop. That is what this lens buys you over the f/1.4 primes everyone else carries, and in 2004, when Cosina shipped the original Nokton 35mm f/1.2 Aspherical, it was the fastest 35mm ever screwed onto a Leica M body. Faster glass has come since. But for a long stretch this was the honest answer to the dead-of-night problem: ISO 400 loaded, no flash, the meter telling you it can't be done.

Wide open it is not clinical, and it was never trying to be. At f/1.2 there is a visible glow, a soft halo blooming around highlights and a drop in contrast that flatters skin and turns streetlights into orbs. You'll also see some purple fringing on hard edges against bright backgrounds, which is the price of that speed. Stop down to roughly f/2.5 and the frame snaps sharp corner to corner, the aspherical surfaces finally earning their keep once the smaller opening crops out the spherical aberration that caused the glow. Below f/2 it's a dreamy portrait lens. Above it, a sharp documentary 35. A rounded twelve-blade diaphragm (present from version one in 2004) keeps out-of-focus highlights circular well past wide open, so stopped-down points of light stay round instead of hardening into polygons.

The original aspherical element went out of production, so the optical formula has been quietly reworked across four versions. The first two are heavier ten-element designs. The version III from 2020 dropped to nine elements and shed about a third of the weight, and a version IV arrived in 2025, lighter again. They all keep the f/1.2 maximum and the rangefinder coupling, and they focus close: the later ones reach 0.5m at the barrel, though the M coupling only ranges to 0.7m, so the last 20cm is live-view or zone-focus territory.

The buyers are street and reportage shooters who work in bad light and want Leica rendering without Leica money. The lens people cross-shop it against is the Summilux 35mm f/1.4 ASPH, which costs several times more and gives you a stop less. The Summilux is the cleaner performer wide open; the Nokton is faster and a fraction of the price, and plenty of working photographers decide that trade lands in their favor. Voigtlander's own 35mm f/1.4 Nokton Classic is the internal rival, smaller and cheaper but a stop slower and softer.

If there's a real knock, it's the bulk and the long focus throw of the earlier versions, and that f/1.2 haze if you wanted crisp at full bore. Note that the focus shift its 50mm f/1.2 sibling is known for does not really show up here; this 35 is the well-behaved one.

When you're running it at f/1.2 in a black room, don't meter the whole scene. Meter the one shadow you actually care about and let Zone Light Meter place that reading where you want it on the curve. The 52mm thread takes standard filters if you ever need an ND to drag the shutter, but at this aperture, in this dark, the wide aperture is the only filter you came for.
