I'm using the FUJINON LENS XF50-140mmF2.8 R LM OIS WR on a XT-3. Have both for a few months and been very happy, until a few days ago. After I switch the camera on, I get this wizz sound on the lense that doesn't stop. It wasn't always like that, so I wonder whether there's a problem with the lense, or whether I accidentally changed a camera setting that triggers this. My apologies in advance if this is an inappropriate or otherwise stupid question. I'm trying to avoid having to trek back to the dealership (different city etc etc), unless there's genuine cause for concern. Any comments would be much appreciated.
