I was going though some of my older gear and found a Promaster 5750 Digital Flash with Nikon Module. Does anyone know if this older flash unit will work with the newer Nikon digital cameras like my D7200.
Some older flash units will work, but not all are capable of TTL. I have two Nikon SB-28 units which will work manually but don't offer TTL with my current DSLR's.
