Very strange, because I bought it as new in 2020 together with my A7R II, and I have used it with more than a dozen Voigtländer lenses. I have never noticed any vignetting anywhere, not even with the 15mm Super Wide Heliar.
You are right, I overlooked the “II” mark in the photo. I just checked my Amazon order, and it is listed correctly there.
I confused it with the Close Focus version. My apologies. The color rendition is also what made me think it was the same version.
