EF is now out of patent.
EF-S is still protected.
So officially BMD can never say it’s supported.
So broadly speaking you can put an EF-S mount on an EF mount BMD camera.
Some lenses may not cover though. So the 17-55 F2.8 vignettes a little in the middle of the zoom range on my G2 Ursa Mini.
But it still works. It’s just the corners go a bit dark in the middle.
