It seems writing reviews is a no-win. If you don't see a weakness, you are called a fanboi, and if you do call it, it is called sour grapes. I am not an optical perfection ayatollah, else I would have kept my FE55 for example. Yes, fast lenses have some CA, including the 'Lux 50 and 'Cron 75 APO (!), or the ZE 35 f:1.4, all of which I have owned and shot. The ZM 35 has, and I can prove it easily, more CA than I thought a modern-day lens of that price range should have. The same is true with flare, BTW.
That said, I bought one and I love it, so it is defintely not sour grapes. Maybe I am just trying to be very mindful in my reviews of not overpromising and getting other guys to spend their hard-earned and then be disappointed.
