Hi, I'm coming from a professional Nikon's system to try Sony A7rII. I'm more or less satisfied of performance of my A7rII with lens adapter (commlite). I'll maintain double brand for a while, because A7rII autofocus can't challenge with nikon's speed and low light performance (I hope on A7 third series.. otherwise I will not switch to sony). Sometime I use remote flashes to have some backlight effect, with Yongnuo YN622 triggers and my nikon SB910s. I would like to trigger my nikon flashes also with the A7rII, I can do with my old RF-603 modified for sony. But with that solution I cant modify the power of flash from the trigger like with YN622 on nikon (I have no interest to use TTL, manual regulation are great) Have anybody tried to use crossbrand flashes with Godox X1 system? My intent is to buy one X1t-S, and two X1r-N to trigger nikon flashes with my sony and regulate power settings from transmitter. Can it work? Thanks
