P: Tethered Shooting with Fuji GFX100S broken since 14.4 & 14.5

[Eik0nic]

So ever sice the update to LrC 14.4 the shutter button stopped working with tethered shooting. I've been using Lightroom to shoot tethered for years with my GFX100S and MBP M2 Max with no issue. I used the GFX tether plugin, then Fuji's Tether App and have both still installed. Whenever I update LrC to 14.4 - or now 14.5 the shutter button in Lightroom just stops working. I get accurate readings of the camera's settings, even live view within Lightroom and I can still manually release the camera's shutter button, but that kind of defeats the purpose, especially with the kind of sets I work with.

I've tried disabling both Fuji's tether plugin and tether app in Lightroom's plugin manager, did all kinds of reboots in combination with disabling one, then the other, or both plugins but nothing works. The camera's firmware is up to date and I'm on macOS Sequoia 15.6. The only thing that gets Lightroom to work reliably again with tethered shooting, is downgrading to 14.3.1. Anybody got any ideas?

Hey, @corporatedrone. Welcome to the Lightroom Classic Community. I'll help you figure this out. 

Rolling back to 14.3.1 may not help native tethering, as GFX100S requires 14.4 and later versions of Lightroom Classic.

GFX100S

14.4

If you roll back to 14.3 or earlier versions, you'll have to use the FujiFilm plugins. Head here to learn more: https://adobe.ly/4lythi5

For now, try removing any third-party plugins for tethering from Lightroom Classic and following the second (manual) method from this article: https://adobe.ly/4fOPxm4 to reset Lightroom Classic's preferences after removing the plugins. 

Let me know how it goes. Thanks!

Hi Sameer, thanks for the quick response. I've updated to 14.5 again, removed all third party plugins and deleted the com.adobe.LightroomClassicCC7.plist file. I just hooked up the camera, started LrC and get the tether panel with the camera's settings, but no live view and still no working shutter button, unfortunately 😞

Forgot to mention you, @Sameer K

Hey, @corporatedrone. Thanks for the updates. The native tethering support for Fujifilm cameras is pretty new, so this may require the team's attention. Could you record your set-up and workflow with Lightroom Classic and how the camera is connected and set up? I'll share this with the team for review. 

Thanks!

Hi @Sameer K ,

thanks for following up on this. So like I mentioned, I have a Fujifilm GFX100S (firmware 2.13) connected via a Tethertools USB-C cable to my MacBook Pro with an M2 Max Chipset and 64GB of RAM. The OS is currently on MacOc Sequoia 15.6. The camera's connection mode is set to USB Auto and the destination folder for tethered capture in Lightroom is set to a local folder on the MacBook's internal SSD where there's plenty of room.

The camera is set to manual mode (M) and AF-M,. The lens right now, although I've tried several, is a 63mm f/2.8 prime.

That's all I can think of right now - do you need anything else?

Hi @Sameer K 

are there any updates on this issue? We've tried connecting the camera to several devices running the latest version of LrC, but had no luck with tethering. I'd hate having to switch to a different software, but switching cameras is honestly much more expensive.

Thanks
