Fast f/1.8 maximum aperture benefits working in difficult lighting conditions.
One aspherical is featured to control spherical aberrations and distortion for improved sharpness and clarity.
Manual focus design enables a minimum focusing distance of 1.6', and it is rangefinder coupled for accurate focusing to 2.3'.
Built-in, non-removable lens hood helps to prevent lens flare and ghosting for increased contrast and color fidelity when working in strongly lit conditions.

I bought this lens for use with Fujifilm XT-3. ...

I bought this lens for use with Fujifilm XT-3. Focus peaking is very hard to do unlike other lenses like Voigtlander 58 1.4. The distance scale seems off by 1 or 2 meters! For example, if I want to focus at 3 meters, I must set the distance on the lens at about 1.2 meters. Why is this happening? Could it be because of the adapter? I am using K&F Concept Leica M to Fuji X adapter.
Asked by: Andrey
Yes, the K&F Concept Leica M to Fuji X adapter, is causing the "distance Scale" on the Voigtlander Ultron 21mm f/1.8 Lens to be inaccurate.

I had a 21mm voigtlander color skopar lens which when mounted on a m10 had bad purple color vignetting. Does this lens have the same or similar problems?
Asked by: David
The Voigtlander Ultron 21mm f/1.8 Lens has some lateral color fringes (secondary lateral chromatic aberration), visible if you look for this sort of thing when shot digitally, but otherwise it's invisible for normal use.

I'm wondering whether this lens might be a good choice for my full-frame Pentax K-1? I realise I'd also need an M-adapter. Tnx!
Asked by: Robert
The Voigtlander Ultron 21mm f/1.8 Lens is a sharp manual lens. Note we do not carry a M mount lens to K mount camera.

Is it coupled with the Leica M10 range finder?

Is it coupled with the Leica M10 range finder?
Asked by: Anonymous
Wrong answer above. The widest FOV of the built in VF is 28mm, but you could use that if you want, even though the image will show more than is indicated in the VF. You would need to use an external 21mm VF in order to be accurate, and the Ultron will be accurately coupled to it, subject to the parallax inherent in all rangefinders.
