A7S II - 4k on board

Will be interesting to see how the new A7sII does with the 4k onboard capture. My A7RII got pretty hot shooting 4k and shut down a few times after 20+ minutes in the sun. But I left it in the hot tropical sun to get some time lapse.
Almost 1 year later I'm still very impressed with the moonlight video using the A7s, and the II supposedly has even more improvements in noise reduction. If the SAVC-S with S-Log can hold the 13 stops underwater, it would be a nice compact rig for shooters. Still the lens department is lacking and the Sony zooms aren't that sharp!

Unfortunately the XAVC-S codec in 4k (100mbps) does not allow for the same level of post flexibility / grading at the HD version (50mbps). Main reason being that the 'equivalent' data rate needed for 4k is roughly 4x that of HD (4x the pixels) - so it would need ~200mbps or better compression in order to have the same post flexibility. While I haven't tested it myself, I have heard this from multiple folks shooting the A7RII - this is a sad realization for me as I went for the smallHD502 over the Shogun betting that the A7SII would have 'as good' 4k codec quality as HD (which by the way is excellent). Of course you can downconvert the 4k footage in post which should be great to grade (oversampled 1080p) but it kind of defeats the point.

Doesn't mean I'm not going to get the A7S II though!

The question is Drew, can it get a decent wide angle white balance? How does your a7rII do? Coming from canon dslr, is tough to give that up.

I'm usually a make it blue water, natural light with occasional filter use kinda guy, and rely on Resolve to perform color magic to get the colors I want. The Canon DSLR have the WB edge, but 4k and lower noise isn't something to sneeze at. Nothing on the lower side of $3k shoots 4k video with this sort of low light performance in-cam.
Then there's the issue with limited lens choice for wide angle. Fortunately, I have the old Nikonos 15mm sitting around. And the new 16-35 is good for video, but so so for the A7RII pics. Pick your poison as it were.

I am starting to think that the 1dxII might be looming for me. if that can have 4k @ 60p, and focus peaking, I think I might be sold. Although wish it was in the smaller form factor as the 5d...and in all reality, I just wish that 5d4 would just come out, but I have a feeling Canon is going to protect their cinema line. Have you ever shot the C300 underwater? And if so, how is the WB with that?

Well once the budget opens up, so do the options. I haven't shot with the C300II underwater but I have with the C300. The colors are good (especially out to a RAW recorder) but frame rates were limited in 4k. The C300II changes that and allows 4k onboard. Not sure if the Gates housing will fit though, since it is slightly bigger.
Still depends on what you are shooting. There's also the Red Raven and Sony FS7 as well. And we haven't even decided on the housing yet! No doubt the C300II is known for reliability and the depth of the EF lens collection is awesome, not to mention cheaper media compared to a Red MiniMag.

The Sony A7sII is all about low noise, dynamic range, compactness and stills flexibility for less than $3k. Sony color science has always been a bit contentious for underwater use, but it's decent down to 40ft.
