besides an X-H1 with the 23mm f/1,4, I shoot with a Voigtländer 21mm f/3.5 Color Skopar Asph and a 40mm f/1.2 Nokton Asph both on Sony A7iii.
I also shoot with Leica M6 and M9 with native 28mm and 50mm Summicron glass.
In the past, with a Sony A7ii, I have used Zeiss 21mm f/4.0 Loxia and 35mm f/2.0 Loxia and of these two lenses eventually I regret the 21mm.
After this premise, I can say that the Voigtländer lenses are very close to the Leica and Zeiss quality and I really appreciate the result, you have to be really finicky to see a big difference.
Vs the Fujinon 23 f/1.4 I prefer the rendition of Voigtländer lenses and therefore I am planning to sell it and buy the 35mm f/2.0 Ultron.
Just to get an idea you can pick-up those photos taken with Voigtländer lenses on my two Flickr acts : srsatvs and Svend RS.
