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.

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.
