I tested a bit webCam X, but it had a lots' of room for improvment.
i had x-t4 but ... seems that i connected my old fujifilm s7000 (year 2005 when fuji allow people to use their bridge like webcam).
we need more resolution, actually is embarassing to have so low resolution, especially that i connected by usb 3.2 connection, internal it had a encoder hardware for h264/265)
please enable video mode, to use noise reduction and more features from video mode
add ability to change Iso, speed, iris from interface, it's annoing to change gears position, turno off, turn on to see t
