Yes, provided the mount matches: the body simply uses the middle of a larger image circle. The reverse does not hold, and the figure that decides either direction is the image circle rather than the mount.
Mount first, image circle second. Both are published, and confusing them is the usual source of a wrong purchase.
What the mount settles
Whether the lens attaches at all. It is proprietary to the camera maker and shared between that maker’s own formats: the designations in this catalogue’s titles — nine print EF, six EF-S, six E-Mount, five RF, four FE, three RF-S — belong to eight owners and no shared document.
Crucially, a single maker often uses one mount across both frame sizes. That is why a lens can attach and still be wrong for the body.
What the image circle settles
Whether the projection covers the sensor behind it. A lens built for the larger frame covers the smaller one with room to spare; a lens built for the smaller frame does not cover the larger, and the corners fall dark.
Reading it on a listing
Makers signal it in the designation rather than in a figure: the suffix that marks a lens as built for the smaller format — EF-S and RF-S here — is the statement that its circle is the smaller one. Where no suffix appears, the lens covers the larger frame. Six titles in this catalogue carry the first suffix, three the second.
What neither settles
Autofocus behaviour through an adapter, which belongs to the adapter; and sharpness at the edges, which is not published in a form two lenses can be compared on.
What people ask before they commit
Do I lose anything by using the middle of the circle?
Field of view, which narrows because the sensor takes a smaller rectangle out of the same projection. You also carry a lens built to cover more than the body needs, which usually means more glass and more weight than an equivalent lens designed for the smaller format.
What happens the other way round?
The lens illuminates only part of the larger frame, so the corners go dark. Bodies that anticipate this offer a crop mode that reads a smaller area of the sensor, which produces a correct picture at a lower pixel count — and that mode is published per body rather than implied by the mount.
