I was fiddling with the GF670 idly when I heard a light snap that sounded like something got detached (not that something broke, I think). Now the lens doesn't return to infinity. Tension stops it at 3m or so, and I don't want to force it.

It's hard to see what's happening in there, but I can vaguely see that the two levers/hooks affixed to the front of the lens that connects to the rest of the RF mechanism are now detached. (Circled in the attached photos.) And I can't close the camera up.

Does anyone have experience with this problem? Thanks.

The video definitely helps. Thanks! I hope I can fix it myself.

I am trying to get a tool that turns the pictured screw. What is it called?

A spanner, I think...

Practice with it a bit; that tool can cause more damage than you can imagine if you try to use it casually...

Kino, thanks. I tried this tool and it sort of worked the first time, but it wasn't quite pointy enough to grab the screw tightly. I thought about sharpening the tips somehow. Maybe that's what I'll do.

Is there a dedicated tool for this kind of screw? Or is it non-standard and exclusive to Fuji?

I am sure Fuji trained repair people had a custom spanner for just that screw, but the odds of finding and purchasing it are slim to none.

Snap/retaining ring pliers might work better for you: https://www.zoro.com/channellock-re...MIzuCAmdOH4wIVFo_ICh3ggQnGEAQYAyABEgJGRPD_BwE

They can be found in any automotive parts or tool store.

Thanks Huss. This is the same tool that Kino suggested and that I used the first time. The tips weren't pointy enough to grab the screw well. And the many points and degrees of movement on this wrench made it unstable. Although I did manage to get the screws off eventually, I ended up scratching them a lot, as seen in the photo above, and couldn't screw them back on very tightly.

I am going to try one of the retaining ring pliers Kino suggested and will report my findings for future would-be GF670 repairers... In the video above Mike Eno also made his own spanner.
