Voigtlander Nokton 28mm f/1.5 Aspherical

The Voigtlander Nokton 28mm f/1.5 Aspherical is a wide-angle prime for Leica M full-frame cameras. It fits street, travel and documentary photographers who work with one fixed frame. The f/1.5 aperture also makes it a practical choice in dim interiors and evening streets.

A 28mm frame takes in a person along with the street or room around them. That sense of place suits storytelling images and environmental portraits rather than tight head shots.

Released in 2024, the lens remains in production. The main trade-off is control. Focusing is manual only, and there is no built-in stabilisation. It rewards deliberate shooting over quick capture.

The lens measures 2.13 in (54 mm) across and 1.79 in (45.5 mm) long, so it sits neatly on a rangefinder body. A screw-in filter attaches directly to the 43mm thread on the front.

At 28mm the frame holds a street corner, a café table with the room behind it, or a small group indoors. You change the composition by moving, since the focal length is fixed. A step back takes in more of the room; a step forward tightens the view. That suits photographers who like to work close to their subject.

The f/1.5 aperture is the lens's main asset in poor light. Inside a bar, a church or a night market, it lets you keep shutter speeds usable and ISO settings low.

Wide open at f/1.5, a 28mm still carries depth of field across a scene, so backgrounds stay readable rather than melting away. Even so, the aperture can lift a subject from a busy street backdrop. The closest focus of 1.6 ft (50 cm) lets you step in on a table or a stall while keeping the room in frame.

Twelve blades hold the aperture close to round as you stop down. Out-of-focus lights then render as smooth, even shapes rather than hard-edged polygons. At small apertures that keeps evening scenes looking natural.

There is no stabilisation. Handheld work in dim light therefore rests on the f/1.5 aperture and steady hands. For static subjects, you can also brace the camera or set a faster shutter speed.

The lens has no weather sealing and no fluorine coating. In rain or dust, keep it sheltered. The front element cleans in the ordinary way, with no repellent surface to keep moisture and fingerprints at bay.

Focusing is manual only, with no autofocus motor. You set distance by hand before each frame, which suits considered work but slows fleeting action. On a busy street, pre-setting focus remains a workable habit.

The lens uses ten elements in eight groups. Two of the ten are aspherical, and both are shaped on both faces. Such surfaces are designed to help correct distortion and spherical aberration. That matters for a wide angle, because distortion can bend the straight lines of buildings and doorframes.

Spherical aberration can soften points of light at wide apertures. The aspherical shaping is designed to reduce that fault, which matters most when a lens is used wide open.
