BH #VO4012M • MFR #BA342A
Voigtlander Nokton 40mm f/1.2 Aspherical Lens
Key Features
  • Leica M-Mount Lens
  • Aperture Range: f/1.2 to f/22
  • Two Aspherical Elements
  • Manual Focus Design
Distinguished by its speed, the Nokton 40mm f/1.2 Aspherical from Voigtlander is a short normal prime designed for M-mount rangefinder cameras. Its comfortable focal length pairs with an impressively fast f/1.2 maximum aperture to enable notable control over depth of field for producing shallow depth of field imagery, and this aperture also benefits working in difficult lighting. Complementing the fast design is an optical layout that uses two aspherical elements to suppress spherical aberrations and distortion for notable sharpness, clarity, and accurate rendering. The lens's manual focus design permits working with subjects as close as 1.6' away, and it is also rangefinder coupled to 2.3' for working with optical focusing systems.

Voigtlander Nokton 40mm f/1.2 Aspherical Overview

Distinguished by its speed, the Nokton 40mm f/1.2 Aspherical from Voigtlander is a short normal prime designed for M-mount rangefinder cameras. Its comfortable focal length pairs with an impressively fast f/1.2 maximum aperture to enable notable control over depth of field for producing shallow depth of field imagery, and this aperture also benefits working in difficult lighting. Complementing the fast design is an optical layout that uses two aspherical elements to suppress spherical aberrations and distortion for notable sharpness, clarity, and accurate rendering. The lens's manual focus design permits working with subjects as close as 1.6' away, and it is also rangefinder coupled to 2.3' for working with optical focusing systems.

Unique 40mm focal length offers a 55° angle of view that is slightly wider than the classic 50mm length, yet narrower than the standard 35mm wide-angle.
Bright, fast f/1.2 maximum aperture affords extensive control over depth of field for selective focus techniques, and also benefits working in low-light conditions.
Two aspherical elements are featured in the optical design to control spherical aberrations and improve clarity, sharpness, and resolution.
Manual focus design permits smooth, refined control along with a minimum focusing distance of 1.6'.
Focus coupled to 2.3' for working with an M-mount rangefinder's optical focusing system.
Rounded ten-blade diaphragm contributes to a smooth quality of bokeh.
Compatible with optional LH-8 lens hood.

Voigtlander Nokton 40mm f/1.2 Aspherical Lens has a Leica M mount. To use it on the Canon R5 you will need this adapter: Metabones Leica M Lens to Canon RF-mount Camera T Adapter https://www.bhphotovideo.com/c/product/1501857-REG/metabones_mblm_efr_bt1_leica_m_lens_to.html

The Leica mount Voigtlander 40mm f1.2 has red aspherical lettering while none of the others do. Is there a difference?
Asked by: Brent
I am fairly certain this is a design element borrowed from some Leica lenses which have some lettering in an orange color.

Most Leica brand M-mount lenses at best have a minimum focus distance (MFD) of 0.7m. This Nokton's MFD is 0.5m. With a digital M body is the rangefinder coupled to support focusing through the optical viewfinder at focus distances between 0.5m and 0.7m?
Asked by: Andrew
According to our Voigtlander contact, they state on most Leica M-mount cameras, you will need to use the LCD screen to obtain absolute closest focus. While a few cameras such as the Leica MP may allow you to focus a bit closer due to its redesigned finder, it is still recommended to use the LCD screen for the most accurate focus when focusing at the lens' minimum focus distance.

Are there issues with close focussing on a film M like the M4 since minimum focus distance is closer on the lens than the camera allows?
Asked by: David
One can focus down to the minimum focusing distance of the Voigtlander Nokton 40mm f/1.2 Aspherical Lens when used on a film Leica M like the M4. The issue is you will have no visual as the rangefinder focuser does not focus this close. So while you can focus that close, you will not have the ability to confirm that your subject is in focus.

I am assuming that this lens would work with the fuji m to x adapter and a x pro 3? I'd like to try it with focus peaking. I'm older, and concerned about manual focus. Any thoughts on using focus peaking in a Fuji x pro 3?
Asked by: Peter
Focus peaking on the Fuji Xpro 3 does work well with Voigtlander lenses with M mount used with the adapter to Fuji X. There are also other aids you can use to manual focus that also help for example the manual focus assist zoom function.

Sony E vs M mount version: There's two versions and I want to mount to new fujifilm xt4 with adapter. Sony E mount costs more, but I don't know if M mount will perform differently? Please help! I'm new to photography, as of last week.
Asked by: Wyatt
Unfortunately, the Sony E-Mount version of this lens cannot be adapted to the Fujfilm X-T4. That being said, your best bet is to utilize the Leica M mount version with the Metabones Leica M Lens to FUJIFILM X-Mount Camera T Adapter (Black), MEMBLMXBT1. https://bhpho.to/2BMHY17
