It's recognizable as a Voigtlander Nokton lens, and is made to communicate with the camera, alas only starting with X-E4 or newer. Build quality, looks and functionality are all good. Also nice colors. And while it has that Voigtlander "character", the lens is NOT sharp. For me that's a no-no. I get better results with 35mm f/.95 Mitakon. So the Nokton was returned, thanks to the great seller. I honestly expected better at that price point. Thinking about 35mm f/0.9 but that's almost 3 times the price..
