How to shoot TTL? (a7r4, UWT, Z330)

Also, I am thinking of getting the Inon Z330 strobes and am confused about what to do with the Advanced Cancel Circuit Switch. Does it stay neutral or locked down or locked up so that you can still use the compensation dial on the Inon strobes?

Shooting TTL with UWT Converter, better adjust (+/-)Flash Exposure Compensation by camera menu scale, it gives much more adequate and wide effect than Z330 right dial for this aim. You will see it on practice. I advice to keep the strobe right dial at zero correction ("12 o'clock" position) and use only camera controls for adjustment. This case you will clearly understand the Flash Exp Compensation effect. Using this concrete conception and synchronizing by fiber optics, you can keep Z330 magnet Up or Down, no difference for shooting.

Thanks Chris and Pavel.

I assume that the ACC is more helpful when using a camera with a flash built in so as to save the camera's battery from firing its own flash. Which is why it is not very relevant for using a trigger?

It clearly is faster to adjust the flash compensation via the camera in one step unless you need one flash to put out less power than the other.
