My Rebel certainly does "throw away" the part of the FF image circle that does not fit onto the smaller sensor.

Believe what you will. It doesn't.

OK, if your Rebel throws away anything so does your FF. Lenses produce a circular image which is projected on a rectangular sensor. Some light is ignored because one is round ant the other ain't.

The question I asked did not relate to differences between APS-C vs FF cameras. It was about EF-S vs EF lenses with the same focal length dialed in and on the same APS-C camera, identically placed, seeing the exact same subject. Are the resulting images different?
Sorry if I appear to be obtuse. This entire discussion has gone off into the technical weeds on bunny trails several times, where the essential question is simple.

And the answer is no, a 70 mm lens is a 70mm lens. It will provide the exact same magnification. It only makes a difference when you are talking about the size of the format.
