Hi All, I like to ask if it is possible to power up the Nikon SB800 by MKZ3 and Quantum 2x2. From what I understand, the MKZ3 is designed for Quantum Battery 1+ series and the connection is via RCA. For the Quantum 2x2, the connection is via DIN and the cable usable is the CKE. Just a thought because I got a Quantum 2x2 and CKE cable, but the set back is that I still need 4 AA size batteries for my SB800 in order to use it. Please share your thought on this. Thank you very much.
