Tethered Shooting with Canon EOS R

I've noticed maybe a problem to try tethered shooting with the Canon EOS R.

If I connect the camera with my MacBook Pro with High Sierra and start the LiveView in Capture One Pro 12 the back screen and the electronic viewfinder doesn't show anything. No image now menu nothing. All the functions of the camera are off, too. Only the Touch Bar on the back which I use for ISO works. No dials, no focus back button, no shutter or the adapter with the command ring is working.

If I stop the LiveView Mode the buttons and dials on the camera work. The adapter ring I used for the aperture doesn't and the back screen and viewfinder of the camera doesn't work, too.

Anybody has the same issues?

This functions really has to work for me.

I suggest you contact support over these issues. Obviously the Canon EOS R is a new type of animal in the zoo and not all features are ironed out yet.

I read some reports on slow tethering as well.

If you hear back, we would love to hear from you again.

Thank you I've contacted the support this morning. I will answer here if I have any solutions.

Yes tethering sometimes is slow, I thought it's the high data, but wondering because it's USB-C. But maybe it could be the cable.

If it is a USB 3 type connection, on your computer and camera, make sure to use a high quality cable with a max. length of 3 meters or 10 feet, attached directly to the computer.

I've ordered a cable from tethered tools with 4.6 meters hope it will work.If not I will change to a shorter length.
For testing yesterday I used the short cable which was delivered with the camera. This should work, too.

Not the cable, I was tethering with a 2 foot usb c cable and it was markedly slower than the Nikon D810 files which are bigger and were going through a 4 metre USB 2 cable. They start out at a reasonable speed but then slow down and come in erratically.

I have the same issue… and also the camera doesn't show the preview image on the back screen… did you notice this?

No preview during tethering do you mean?

I think that is what the is meant. There was never an image on the LCD of the camera during tethering IIRC.

Yes exactly, no preview on the rear camera lcd during tethering…
This, for me, makes very difficult to shot in this way…

Preview is working fine for me while tethering.

Still slow though. Smaller files plus usb C and they should be at least as fast and consistent as my Nikon D810.

The answer of the support was...

They think this is by hardware design how the camera works when you enable liveview - that controls are then transferred to the software from camera. That the camera cannot operate with controls at the same time live view is transferred to a computer - then the camera control protecol is also transferred.

I will ask my colleagues if this is so and will get back to you if this is not intentional from software.


So how is it possible that awoof could use the liveview and use the preferences on camera at the same time and has preview on camera? Are you shure the liveview mode was enabled?

If I use the tethered tools USB-C to USB-C cable in 4.6 meters it's the same. So it's not the cable!

Could user awoof confirm or deny that he referred to the EOS R?
