Has shutter button come off your Fuji GF670?
Recently the shutter-release button came unscrewed from my Fuji GF670W and was lost. I know this has happened occasionally to others, whether it's my model or the GF670, The Bessa 667, or the Bessa 667W.
After trying almost every option, I resigned myself to the reality of no available parts--not through Fujifilm, Voigtlander, Cosina, anyplace. So the camera is now at SK Grimes, waiting for them to fabricate the two parts that make up the mechanism.
If this has happened to your Fuji, please let me know. Grimes can easily fabricate the threaded metal disc that surrounds the shutter-release button. But they're not certain about the button itself unless they can see what it looks like and how exactly it attaches to the shutter-release shaft in the camera. Thanks.
Here's a photo of my camera.
