v6II + rf60x with SIGMA dp2 Merrill SDQ
I have a v6II + rf60x to use with the sigma dp2 merril and sd quattro in TTL. But I can not do it. The system works well in manual mode but the automatic ttl management in the camera does not work. I tried the two firmware available for sigma sig.1.001 and 1.002. I use 001 because 002 continuously disconnects v6ii. Tips for working in full auto with sigma?
