Well, that's why I suggested Kamlan in the first place. It is relatively inexpensive and IMO better than let's say Komine or Kiron 28/2 on the crop. If we talk about other vintage lenses mentioned ...

I have completely different impression. If closed down a bit, it is very sharp. So, yours is probably a lemon. If not Kamlan, I would recommend Voigtländer Ultron 28mm f/2.0: https://phillipreeve.n ...

Konica AR 35/2 is quite a rare lens and therefore expensive and not easy to find. It is excellent though, at least my copy is one of the sharpest fast 35s that I had, though it is quite beaten up.
