Fuji is going to fix it for free. I'm always very careful when swapping lens. I've been shooting with Canon L lenses for years, never had this kind of problem, especially only after a few weeks of use. My guess - as the post reads - is that it's dried glue which starts peeling off after use.

Hello hello, I returned the first Fuji XF 90mm lens I ordered because it had dust inside right out of the box. The replacement was clean but after 3 months: specks of dust all over – I counted around 20. I am aware this does not affect image quality but for a weather resistant (WR) lens, I find it hard to accept. Never had such problems with my Canon L lenses (that I have used extensively in all conditions for 10 years) or my other WR XF lenses (35mm and 16mm). I’ll pay the Fuji Service center a visit tomorrow and ask for a replacement, let’s see what they say… My guess is that dust settles in during the manufacturing process and starts spreading after use Photo there: http://www.benoa.net/2017/06/xf-90mm-and-dust.html
