I have recently sold all my Yongnuo speedlite kit and bought into Godox, for their integrated radio system.
I have, so far, an AD200 strobe, a TT685-F speedlight and an X1T-F controller (Fuji system). All work absolutely flawlessly together, but I could do with another speedlight, at least until I can justify a second AD200 😉.
My quandary is, should I get another TT685 (TTL)? or will the TT600 (non-TTL), at half the cost, suffice?
I expect to use the two speedlights, strapped together, in a modifier on those occasions that I need a bit more grunt as a fill/edge light to compliment the AD200.
If used thusly, will TTL calculate the flash exposure correctly if one speedlight is non-TTL? In other words, will it compensate for the lack of adjustment? Or should I bite the bullet and stop expecting miracles, even from this excellent system?
