I have a black Fuji X-T1 at firmware version 3.0. I want to record a video using an external audio source, fed from an audio interface through a standard 3.5mm stereo jack (like the one you'd use for headphones).
I have my mic/remote option set to "mic", obviously.
When I connect the cable on the camera end, it asks me to check the setting again, which I did. Then, when I connect the other end of the cable to the audio interface, the camera suddenly starts taking a bulb exposure. As soon as I unplug the cable from the audio interface, the exposure is stopped.
Am I doing something wrong? I'd expect the camera to just do nothing until I actually start recording a video.
