P: Canon tethering stopped working after updating to Lightroom Classic v15.4

Since I first updated to LR Classic v15.1 I’ve had one tethering problem with my Canon 5D Mark IV, I can’t adjust the focus. Shifting the autofocus point is almost impossible because the option turns off in a flash. It’s not the camera. Focus works fine when not tethering. I just upgraded to 15.6 which did not fix the problem. Anyone else experiencing this?

Canon 5d mk4 has now stopped working with Lightroom , I cannot tether the camera , or download images , it just does not see the camera , which was fine until this update !!!   what are we actually paying for apart from stress Reading these comments looks like Adobe do not test FULLY before they update ;    PLEASE get it fixed fast or its goodbye from me which is sad as I have been a user of Lightroom for over 10yrs `. doubt this will get a reply 

I just received the r6 mark iii and cannot tether shoot at all with lightroom. I’ve turned on Canon SDK for Tethering and that made it worse as the software does not connect to Lightroom at all. EOS Utility can connect to the camera, but Lightroom cannot even detect the camera. 

FINALLY!
Tuesday 29 Sept 2026 
Lightroom Classic updates to v15.6 
And finally the Canon Eos R6 iii is working with tethered capture 
AT LAAAST!

Please pass our thanks to whoever, eventually, made this a priority 

The new cameras that we all bought ages ago can now – FINALLY! – be used in our professional workflow 

 

Connect my canon r5 mkii to Lightroom tethered capture. It connects and can shoot via the tethered button in Lightroom but no images are transferred over and nothing appears in the library. I’ve tired every solution online to fix it but nothing works. It was fine before the latest Lightroom update.

I managed to connect with an actual person working for Adobe this morning. I used the online chat facility on their help pages which is very hard to find… and you have to chat with an AI Bot for several comments, before it offers you the option to connect with a human. 

I raised the issue of R6 Mark iii still not tethering with Lightroom Classic on a Mac (even with all latest updates of everything)

Thank you for the time. Yes its a reported and the bug has been raised already with the engineering team. Our team in working on the update. And it should be fix in upcoming major update.

Thank you. Canon R6 Mark iii is currently listed as supported on the Lighroom web pages. Please can this be corrected.

Do you have a timescale for the update?

Sure, I will share the details with team to update it. I apologize but the exact time is not known to us as it depends upon testing, development, and management. But you may expect it in the upcoming update or the adobe max update which will be major release

You said:

Thank you for your help. Please can you stress the importance of this update. Many users are currently unable to use their new cameras for theior professional work. Myself included.

You are most welcome! Yes I will surely update the team about the situation and prioritize the issue so that this can be fixed asap.
 

Exactly the same issue here 
I’ve raised it repeatedly in these forums 
Even after yesterday’s update to Classic 15.5.1
Still nothing 
SUPER FRUSTRATED 
Lovely new camera – that I can’t use for most of my work 


 

No need for anyone to clarify if the R6 Mark III is supported, you can always go to https://helpx.adobe.com/lightroom-classic/desktop/kb/tethered-camera-support.html and get the latest information.

As far as your other issues, you probably want to file a formal bug report.

Tethering with my Canon EOS R6 Mark III is still not working in Lightroom Classic 15.5, despite Adobe stating that the Canon tethering issue had been fixed.

In fact, the situation is now worse than it was in Lightroom Classic 15.4. With 15.4, I could at least see the camera's Live View. In 15.5, I get nothing. Lightroom can see and display my camera settings, but I cannot actually use tethering or control the camera from Lightroom.

I have already ruled out the camera and cable as the cause:

• The camera firmware is fully up to date.
• Canon EOS Utility recognizes the camera and works correctly.
• The USB tethering cable is working properly.
• The camera itself is therefore clearly communicating with the computer.

I also tried using the SDK option, but in that case Lightroom Classic does not recognize the camera at all.

So, despite the release notes indicating that the Canon tethering bug was fixed, the Canon R6 Mark III is still effectively unusable for tethered shooting in Lightroom Classic 15.5 — and compared with 15.4, the situation has actually regressed.

This is seriously affecting my work. Tethered shooting is not an optional feature for me; it is an essential part of my professional workflow. I have already spent significant time troubleshooting an issue that should have been resolved by this update.

Please investigate the R6 Mark III tethering implementation specifically and provide a real fix as soon as possible.

I would also appreciate clarification on whether the Canon R6 Mark III is officially supported for tethered shooting in Lightroom Classic 15.5, and if so, why the functionality is still broken despite the claimed fix.

Canon R6 Mark III here and it’s not working. It detects the camera and I’m able to show live view and trigger the shutter button via Lightroom, but images are never transferred to macOS. Image counter on camera keeps flashing forever, like it’s trying to save the image but never ends.

Tried the “Canon SDK for Tethering” but with that option enabled the camera isn’t detected at all in Lightroom.

I’m using Lightroom Classic v15.5 in macOS.
