CHG CANON - That was the problem. I checked the user manual and on page 72 (I hadn't gotten that far yet), it showed how to change the Aspect Ratio. When I did, the problem was solved. Thanks!
Unfortunately, by using this feature, you're turning your 30MP full frame camera into a 12MP crop sensor camera. That sort of defeats the whole purpose of getting a full frame camera!
If you want to keep using the 18-400mm lens, you'd be better off with a 24MP 80D or Rebel.
Or trade the lens in on a lens made for the full frame camera, like the 24-250mm someone suggested. That won't get you near the telephoto reach that the 400mm gave you on a crop camera. But Canon has an RF 600mm f/11 coming to a store near you soon, which will be close to equiv. to 400mm on a crop sensor camera.

I recently acquired a Canon EOS-R camera and I am still learning about its features. I put my favorite lens, a Tamron 18-400, F 3.5-6.3 lens, on it using a Canon adapter. When I take a picture, there is a shadow around the edge as seen in the attached picture. Is there a different adapter I should use or is there a setting on the camera that needs to be changed to eliminate it? Thanks.
Same image cropped. You have an equivalent of the rated mm times 1.6

I’m using Tamron 18-400mm lens on Canon eos R with satisfactory results. I believe that adjustment takes place due to electronic communication between the lens and camera body.
