I am sure there have been lenses in the past which have produced ghost images of some sort. They never produce an image with an off-set copy of the original image like we see here, though.
And it is not just my logic, others have come to the same conclusion. People have even warned about this possibility when the use of beam splitting mirrors was only still a patent application last year or so (yes, you can patent the silliest "don't we know that already?" ideas).
And it surely is not "the lens". Because: A. Lenses just can not cause a double image, and B. Imaging resource showed a comparison from an A55v with the same 18-55 kit lens as on the A560. Ghost flash light images for the A55v, not the A560.
And other lenses from users also show it.

Lenses actually can create double images. It is not common, but it is possible, both in theory and in practice.
Kind regards, Wim
