I bought this as a discrete f2 street lens for XPro3. The reviews on YouTube were largely unflattering, but I liked the size and feel. It’s made in Japan, feels great quality. Yes, it’s a bit slower to focus and a little noisy compared to some, but nothing like as bad as some reviews would suggest. I mainly use it with zone focus in MF, combined with back button focus. I’m very happy with IQ. Only drawback for me is that it is not WR, and I do like shooting in the rain. Since buying it it’s always on my xpro3.
