I have three remote shutter cables, all with the 2.5 mm jack. These cables have worked flawlessly for the last several years with all my Fuji and Canon cameras. Just the other day, they stopped firing the shutter on my XT-2. A half press works as expected, but with the full press nothing happened. All three cables work flawlessly on my XT-10. I have blown out the socket on the camera, and it looks clean. Any ideas would be much appreciated.
