X-s10 with Fujinon 16mm 1.4 autofocus issue

[Etienne B]

Hello. I have a x-s10 that I use multiple lenses with. Yesterday I noticed that with the Fujinon 16mm lens I'm having issues auto-focusing. It works on video but not for still images. When I half press the button it focuses a bit then when I release the button it snaps back to the previous focus point. Even though it manages to focus the image is still blurry. Any ideas please. I already did a a major google search and nobody has mentioned this issue.

Thanks,

Etienne
