Wondering if anyone has used the TTL converter for the Nikon D850 (or D500 or D5) and what you think about its performance. Also would like to hear opinions on switching underwater to manual mode through the camera as opposed to the strobes. Reading the instructions it sounds like I don't have a lot of flexibility in having one strobe stronger than the other unless the system allows me to use on-strobe EV controller. It's a change for me going from manual strobe adjustment to in-camera adjustment so I want to understand what I'm getting into and what potential limitations I'm facing.
Appreciate any feedback. I may be retiring my D7100 Nauticam system soon and move into full frame. I shoot landscape full frame and in-studio full frame and cropped underwater, so I have a crap load of camera gear that I want to standardize.
