The Fujifilm GFX 100s is quite picky with USB-C cables. I have one that works, but the problem is that it’s straight rather than 90 degrees at the camera end. Before purchasing an expensive Tether Tools cable, I wanted to test Wi-Fi tethering speeds. If you only need JPEGs (I noticed low res jpg preview in 2.5s), it might be usable, but RAW capture is far too slow. After noticing that, I checked the GFX 100S Wi-Fi specs, and sure enough, it only supports slow 2.4GHz Wi-Fi. So, I guess I’m ordering the Tether Tools cable after all.
