P: LrC 15.0 Canon cameras (R5, R5 MKII, 5D MKIII) are not recognized for tethering

[nicolase51549506]

Bonjour

Depuis l'installation de la dernière version 15 de lightroom, il est impossible d'utiliser le mode connecter avec mon canon R5

Lightroom détécte un appareil photo mais n'arrive pas à l'identifier.

Pouvez vous régler ce BUG?

Merci

While the camera can intitally be detected, it doesn't reconnect after turning off the power etc. 

The tether bar appears and simply says "no camera detected".

Hey, @grayj7988641. Thanks for reaching out. I'll help you figure this out. 

Please share the system info from Lightroom Classic from Help > System info > Copy and paste into a text document > Upload and attach here.

Check the camera's permissions in the Privacy & Security section in macOS, revoke any previously granted permissions, and see if that helps. Also, as a test, check any other apps that can detect with the Camera, like the EOS Utility. 

Just to be sure, ensure Lightroom Classic has the required permissions on macOS: https://adobe.ly/4hmGnNB

Let me know how it goes.

Thanks!

Hi Sameer, 

Thanks for the reply. 
I've attached an rtf. 

Lightroom has the permissions. Also, I didn't have any issues with this before updating. 
I'm nor sure what you mean by permissions for the camera. Where would I find them? 

EOS Utility functions normally. 

[Sameer K]

Thanks for the confirmation. When you set up tethering in Lightroom Classic, make sure no other services, like the EOS utility, are accessing the camera. 

Let me know how it goes. 

Thanks!

Hi Sameer, 

No other services are active. This is the same as when tehtering using the previous version of Lightroom Classic.

Hello,

I upgraded to LRc 15.0 yesterday evening (on Mac OS 14.7.3).

Since then I can't shoot tethered with my Canon 5D mk III (it was working perfectly fine before the upgrade).

Tried restarting computer, Lightroom, checking cables, nothing to do :

- I start tethered capture ;

- The search panel shows up few seconds (as usually)  ;

- The camera control panel shows up, but stay grayed out with "No camera detected" mention, I join a screenshot.

It's a problem for me, I shoot professionally and I need tethering.

Regards.

If you must still run Sonoma, try updating to 14.7.6 which is the final release.

The new LR Classic does not detect the camera for tethering. I am using the same configuration as I have used with the previous LR version that worked flawlessly. 
I am on Mac OS (Sequoia) and LR Classic 15.

Hi @nicolase51549506, welcome to the community!
Sorry to hear your camera isn’t connecting. Let’s try a few quick steps to rule out some common issues. First, could you try turning off your camera, restarting your computer, and then reconnecting the camera?
If possible, try using another application, like your camera manufacturer’s software, to see if it can detect and capture photos from the tethered camera. Also, please make sure your camera’s firmware is up to date.
If it’s still not working, try using a different USB cable and USB port to see if that helps.
Let us know how it goes!
Thanks,
Alek

Hi @csavules, welcome to the community!
I’ve gone ahead and merged your thread with another one where a user is experiencing a similar issue, so we can keep everything in one place and help confirm if it’s a bug.
When you have a moment, could you share a few more details, like which camera you’re using? Also, were you able to try the troubleshooting steps I mentioned to Nicolase? Let us know if any of those helped or if the issue persists.
Thanks so much!
Alek

Hi there Aleke, I am using a Canon R5.
It worked with the previous LR Classic version. After the update it would not connect. It does see/feel the camera as it reads the card and suggests to import but it fails to connect. I have restarted the computer, the only solution I got was to downgrade and with the older version it worked flawlessly. The tethering works fine with the EOS 3 Canon utility. 
Thank you

Hey, @fred31003809. Thanks for the post. I've merged your post to if this is broader issue with Canon Cameras: https://adobe.ly/47zLXJg

For @fred31003809, as correctly suggested by, @ExedyUSA, please update the macOS to the final release. 

Please check this basic connection flow and check if it helps:

1. Connect the Camera to Lightroom Classic in On state.
2. Launch Tethering.
3. While plugged in, switch the Camera Off and On. 

Let us know how it goes. Thanks!

Please let us know if it helps.

I volunteer at my local library in thier local history department, serving as technical advisor on thier negative scanning project.  Two days ago I was in and updated their computer to LRC 15, from the last version of LRC 14.  Since most of their work is tethered using a Canon R10, I setup the camera for some test shots for a new project , and LRC could not connect with the camera.  Since I did not have time to try to troubleshoot the problem, I reverted LRC back to 14.5.1, where tethering worked, and LRC still could not find the camera.  The computer I was trying to tether to is a MacBook Pro M3 running OS 15 latest version.

I went thru some of the troubleshooting steps, and found that their R10 was using old firmware.  I did not have time to fix that problem, I decided to try tethering at home, with my Canon R8.  I got the same error on both my MacBook Air M2 and my MacMini M1.  Both of my Mac's are running Tahoe Version 26.0.1.  

I did delete the lightroom classic prefrence file, and was able to thether using Canon's Digital Photo Professional 4 software.   That being said everything I try in LRC results in No Camera Detected.

Tried connecting the camera in On state.  LRC did find the camera and tried to download the memory card.  Stopped that tried to tether and got camera not found message.  Disconnected everything, and formatted SD card in camera.  Reconnected and tried to tether, got camera not found message.  Turned camera off, and back on it caused LRC to hang, spinning rainbow wheel, and I needed to close it by force quitting the application.

[grayj7988641]

Just to check, you're saying simply reverting doesn't fix the problem?

[Bobinmacomb]

On the Libraries computer, I tried reverting back to 14.5.1 and the problem presisted.  I did go back today and deleteted the prefrence file, and the problem is still active.  Up to the update they were tethering almost daily.

[robertaa41277535]

I am having the same issue. Stupidly updated last night without reading about the latest release bugs first and now cannot tether my Canon R5 to my Macbook Pro. I had held up off updating to the latest OS because i had read about issues with that but am now doing that just to see if it helps. Am thinking that this is unlikely to be the case though from what i am reading online. Have any of the solutions suggested here worked for anyone? Need to tether for my clients so this is not great, help!

[fred31003809]

Hello @Sameer K, thank you for your replie!

I upgraded Mac OS to 14.8.1, tried your process, nothing changes.

I finally downgraded to Lightroom Classic 14.5.1, everything works again as expected. I'll stick to that version until problem is solved.

Regards,

[csavules]

I have uninstalled the LRC 15 and installed back the old 14.5.1 version from the cloud. It works perfectly. 
Oddly enough with the 15 version the OS does read the files on the card... somehow there is a connection but it fails to detect the camera. Canon camera services were stopped at the time. I manage to connect and shoot tethered only using the 14.5.1 version and the EOS 3 utility. I shoot R5. 
I hope the above helps any of you.

Adding bug number. 

Note: @Sameer K 's workaround instructions in the pinned post work for me in restoring Tether Functionality.

Hello

The best solution is to revert to the previous version of Lightroom while waiting for Adobe to fix the bug in a future update.

[Rgalloway7]

Reverting back to Lightroom 14.5.1 fixed the problem of LR not being able to detect my Cannon R6 and R6MII and 5DMIII. They need to fix the tehering bug in v 15.0
