okay, that is somewhat different from what I envisaged. if you were to 
move the camera in a plane parallel to the plane of focus (or indeed 
the film plane, which is the same in a 35mm camera) then the eye would 
certainly still be in focus.

However most people when reframing do rotate the camera about an axis.

There is a third possibility when using a camera with shift capability, 
of course, which is to shift the lens. This is always in a plane 
parallel to the plane of focus (think about it!) so focus doesn't 
change at all. In fact, by combining camera movement and shift, you can 
keep the lens in the same place and 'shift' the back so the image 
geometry remains identical.
