If that were the case, then moving the camera 24mm (or so) in any
direction would result in a total change of picture, since
according to your claim, everything that was originally visible on
the sensor will have moved 24mm (or so) and will now be off it.
You can test this yourself: put any lens on any camera in your
posession (I suggest a wide-angle). Look through the viewfinder.
Keeping the camera pointing in the same direction, step sideways
one step. Can you still see anything that was originally in the
frame? If so, I'm afraid that your assumption is incorrect.
I just tested it in my studio this afternoon with a view camera.
Focused on a wall and marked the location of a picture on the wall
with a grease pencil on the GG. Moved the back laterally 10mm. Lo
and behold, the picture was now exactly 10mm from the grease pencil
outline. This is the same no matter what lens I put on the camera.
Sorry, but you're wrong.
