Canon's new EOS R is full frame and your EFS lenses are designed for smaller APSC sensors. Your EFS lenses will not full your full frame sensor.
Go to the Canon USA web site: Under “Features” EF-S will work fine. The camera automatically crops the sensor so the lenses work as designed. In my opinion a great feature for photogs with both EF & EF-S and those moving up to full frame. And so what if they don’t fill the sensor. Oh, I guess we are suppose to have a bunch of money to throw at lenses and I am being a bit snarky! I have both EF-S and EF lenses. Just waiting for all the dust to settle before I move up to full frame.
