Old lenses with IS don't use in-body stabilization. Only if you see the (hand)+ symbol in the viewfinder you have both systems going at the same time. It's only RF lenses, and even there, not all.
Interesting. I did not know that. When I tried the 400DOII with an R3, I would hear slight whirring from the camera body when shooting and I just assumed that that was the IBIS in use.
