As to how she did it, you simply buy a plastic insert that's designed for a FF camera, remove the old one from this lens, pop the new FF insert in, and wala, it will fit a FF body. But as pointed out above, you must use the lens with care if you put it on a FF camera because it will interfere with the mirror when zoomed to 10-11 mm.
