As of now Canon eos 5d sr is not supported for tethered shooting, and there is no ETA for it.
You may always refer to the following article to check the Camera supported for tethered shooting : https://helpx.adobe.com/lightroom/kb/tethered-camera-support.html
Please let us know if it helps.
Thank you Tanuj.
Thanks for the quick response, and please tell those smart people to please hurry up and get it done.

The first thing that has to happen is Canon needs to add camera support for the new cameras to their SDK (Software Develoeprs Kit) which is what Adobe uses to attach to Canon cameras.
It appears that the most recent SDK is from Nov 2014 and supported the 7D Mark II that was released the month earlier.
Once the 5Dsr is added to the SDK then it’s usually a few months/releases until Tethering is added.
So right now Adobe is waiting for Canon.
