T4i to 6D

Any given aperture from a specific lens will provide the same exposure on FF and on crop. So, to take the 24-70 f/2.8 example, if I put it on a T4i and set the aperture to f/2.8, and if to get the correct exposure at ISO 100 I need a shutter speed of 1/200, then exactly the same will be true if I put that lens on a 6D.

Do the experiment and report back if you don't agree. Use Av mode, set the aperture and ISO, and see what the cameras tell you the shutter speed should be.

Yes, the depth of field and the field of view will be different on the two cameras with the same lens.
