It kills batteries. If you have moving subjects the data from the pre-flash will be invalid. Also, whatever happened to the decisive moment if you have all these flashes popping off? I'll take straight TTL matrix with fast synch speed or no flash at all. Actually, it's worked quite well for over 60 years without it. Carl S.
