The only attraction with digital on a 500 Series would be if it was square, full format.
As for all those wires on the one in the video, as for pretending 500s were good hand-held, forget it. Mine lived on tripods. Even in a studio, walking around with a 500 on a cable to the flash was silly: you just can't focus well enough, and with digital, it would reveal that even more badly. They are slow cameras for considered working. You want to snap? Use 135 formats or smaller.
