Just a couple quick points:I don't have one, but I have dived quite a lot with a buddy that is shooting an a7rIII. We have done the North Carolina Wreck Shark Shootout (photo/video contest) together the last 3 years (he shot the a7rIII the last 2 years), so I have many evenings of hanging out with him as we both downloaded our day's photos and did our editing to get our submissions ready for the contest. Lots of time to learn about what he's shooting and see the results.
With his a7rIII, he has won a 1st place in one category every year he's shot that camera. The contest only allows you to win one 1st. He won at least one 2nd place each year as well. This year, he won 1st in Best Portfolio, 2nd in Best Wreck, and 3rd in Best Shark.
He shoots with a Nauticam housing, the Sony kit lens (the 28-70mm f/3.5-5.6, I think is what it is), and the Nauticam WACP port. He had some other, better lens with a normal port setup before the WACP came out. But, the WACP with the kit lens gives better results than any better lens and other, more conventional port/dome setup.
The WACP is fantastic for wide angle, close focus wide angle, and, because it supports full zoom-through, it actually works very well for shooting very small subjects as well. I'm not going to say it gives true macro. But, when the camera is giving a 42MP image that is razor sharp, you can crop to still get an excellent "macro-like" result.I believe with this setup, the WACP will allow you to focus on a subject that is right up against the lens/port.
I am planning to upgrade from my m43 rig to FF some time in the next year. My plan is an a7rIII or a7rIV, if it's out by the time I'm ready to buy, and a Nauticam housing. I wanted to go with an Aquatica housing, but I have emailed with one of their engineers and there is no way to use the WACP on an Aquatica housing - and, while I may not spring for the WACP immediately, I do not want to invest in a platform that will preclude me from using it in the future.
The WACP runs around $4K. It is REALLY expensive. BUT, when you factor in the lenses you don't have to purchase, it's actually not THAT expensive. I.e. The WACP + the kit lens is around $4400. If you want good WA, CFWA, and some ability to shoot small subjects, you could easily end up buying at least a WA lens and a macro lens and, with the ports, domes, etc.., to go with them, the total starts getting up around the same price. And, with the WACP, you can shoot WA and zoom in to shoot small stuff all during one dive, without changing any lenses or ports. And, for WA and CFWA, the WACP setup will give sharper images. I'm really not sure how the WACP setup compares to a true macro setup, for shooting macro.
At this year's WSS, he had upgraded to the latest firmware with the Animal Eye AF. He tried it and it did not work as well for him, when trying to focus on sharks, as whatever non-Animal Eye AF he was using. I'm not sure why that is. I speculate that it may have had something to do with the sharks being frequently surrounded by balls of baitfish. Maybe with a hundred eyes in the frame, the camera couldn't decide which one to focus on and was too-often focusing on a baitfish eye instead of the shark. Not sure.
However, I've been trying to find a solution for soft and distorted corners with the 16-35GM
