Hello,
I'm becoming increasingly frustrated with the R6 Mark III. I have tried everything and cannot figure out how to tether to Lightroom classic. I have the most up to date Lightroom Classic...I have the newest firmware on the Canon. The camera is not even being recognized by lightroom. This is literally the only thing I needed this camera to do. Has anyone successfully tethered their camera?
Thanks!

“ I am having the same issue. My comp is not even recognizing the camera - is yours? “
Hoe long is your cable? The standard cable is only 1.0 meters long. It also has baluns to reduce RF interference. Cables without them probably won’t work.

This is my cable https://www.bhphotovideo.com/c/product/1619202-REG/tether_tools_cuc15rt_org_tetherpro_usb_c_to_usb_c...
B and H said to buy this one. It's the same that I use for my 5D Mark IV. I could never shoot with a 2 m cable, not enough slack for me.

This site is not official Canon customer support. For official support call the Canon Customer Care Center at 1-800-OK-CANON, Monday through Friday. On-line support is available 24 hours a day at https://www.usa.canon.com/support.
The R6 Mark III Canon manual at https://cam.start.canon/en/C022/manual/html/UG-11_Reference_0090.html specifies a higher-speed cable than the one in your B&H link. It calls out "Equivalent to USB 10 Gbps (SuperSpeed Plus USB / USB 3.2 Gen 2)" versus the lower-speed 5Gbps cable from B&H. I suggest you find a short compatible full high-quality high-speed USB-C cable and verify functionality with that cable and then find out if you can obtain a longer cable that meets the the Canon speed specifications as outlined in the manual.

Same problem. In Lightroom, I get that small elongated window with the info, 'no camera detected'; below this text, however, is the name of the folder I provided. Furthermore, on the camera info screen, a laptop icon is visible alternately and, very briefly, the normal camera info.

Minor correction: While online support is technically available 24/7, we do not have live agents available 24/7. I didn't want anybody to have their feelings hurt at 3am because our PIXMA team is fast asleep!

Repeating from SarahElliott's thread:
"This site is not official Canon customer support. For official support call the Canon Customer Care Center at 1-800-OK-CANON, Monday through Friday. On-line support is available 24 hours a day at https://www.usa.canon.com/support.

The USB-C specification in the R6 Mark III appears to be the latest and highest quality USB-C available and you'll need to get the right cable to support it. For some time now charging a Canon camera has not worked over USB-A to USB-C cables and more and more devices are moving to the newer and faster standards. I took the chart below from benq.com, who sell projectors, monitors, etc. It doesn't take much work to find out there are a significant number of USB-C cable options. This is also true of HDMI, of course. The Canon manual implies you'll need a USB 3.2 Gen 2 Type-C, and a cable sustaining that for the distance you want, which may imply you might be better off with a USB-4 cable.
I will note that a quick search of cables shows many online cables showing 3.2 capability and compatibility, but that does not imply true native 3.2 Gen-2 Type C certification.

Thanks Stephen - good point!

I suspect that this is a cabling problem. The B&H cable at the link is 25 feet long and is rated at 6 gigabits. It also lacks baluns, which are essential with the camera.
Has the connection been tested with the Canon cable that came with the camera?

I agree Wadizzle, and Camera connectivity is easily tested with a short known-compliant cable.

I had bought (2) 3 meter cables. Neither cable worked. But the cable that came with the camera worked fine.
