I used (for the first time) a Sony A7 IV with the 28-60 in standard port on a trip to Malapascua earlier this year. I don't have the CMC, but did use a Subsee +10 wet lens for macro. Felt that some macro images were slightly soft, but maybe as I gain experience, will learn the right combination of aperture and strobe.. You can see my images from the trip here:

I did not use the WWL-1 B on the thresher sharks, but I will try it on (I hope) tiger and hammerheads in my planned trip to Maldives in early/mid Jan - will post images after.
Cheers,
