I was over on the V6 2 community and when I understand the Nikon SB 28 and the Nikon FBA TDX are not compatible with the V6 to because their analog TTL is this true?


  • If the SB-28 can operate in Nikon's i-TTL then it will work on the V6 II. But if not, then yes, it means that the flash can only operate in analogue TTL.

    V6 Mark I = analogue TTL

    V6 Mark II = digital TTL
