The trigger voltage may be too high for a modern camera...it could fry the camera if so.
Also, skip the Sony flash and get a Godox. All the same features of the Sony and more, at a fraction of the cost. The lithium battery models are the best.
The trigger voltage is no problem and the communications mismatch is harmless. But all automation will be shut down.
I use an old Vivitar 285 for all my various digital cameras. Since the auto exposure is not TTL, that always works as well.
