D3200 with Metz 15 MS-1
I have currently the D3200 body and a Metz 15 MS-1 flash. I am very new to photography, but from trying to learn online I understand that this setup can use a master-slave relationship. What if I wanted to use a commander-remote relationship? Would buying a Debao SU-800 work? Or would I have to buy a whole new body like a D90 or D7000? Thank you in advance.
