Awesome! Thank you guys for all the replies! And oh my goodness.....I would die if that was my camera (im sure the studio was happy).

Gotcha, so you think that would be enough to prevent paint from getting in and keep the camera from getting damage from force impact?

Well I meant either. I prefer using a gimbal but with the water housing that obviously would be too big or most likely cause problems, hence using a glidecam; I meant either one.

Yeah but would that mess up the balance of the gimbal? 

I guess we could make it staged, but I still would want them shooting. I want to make it feel like its real and not staged. I saw some shots from the previous videographer who worked for them and it was very obvious that it was staged. Maybe not to the untrained eye, but to me it was very easy to spot. I'm thinking of using this, but trying to see if there is a more affordable option. https://www.bhphotovideo.com/c/product/1608185-REG/ikelite_71475_200dl_underwater_housing_for.html

This guy I follow did a review 

Well I'll be!
I destroyed the filter.     The edge was soft aluminium so was simple enough to file the edge off and have the glass just fine.
This is going to be fun.     The filter fits right in.    It might be a little loose but once you put a lens on it seems ok.      An EF-S lens doesn't seem to fit (probably for the same reason Canon FF cameras can not mount them).     That means my 18-55 APSC kit lens is out but my EF 100 f2 is ok (for fit at least).
Sticky tape would work well to hold the filter in too I think.
Amazing.     With my A7s and Fotga adapter I am getting auto focus indoors with a 750nm IR filter and can see easily in the EVF!
OP, This will easily take two filters (one inside, one on the lens front though if it is any good or not is another story.
Two snaps.    The filter glass sitting loose in the adapter and one taken with the lens and filter in place auto focused.
This calls for more 43mm filters for me!
Thanks for the thread, this will be fun (though add to more cost I can not afford).
As for the IR image, remember it is just a first snap in the excitement and is with AF at ISO 51200 and 1/15 with a 100mm lens at f2.
Have to check it with my 17 TS-E too!

Better to wait for the a7s4, which will fix some of the problems with the a7s3.
There are ALWAYS problems.

The a7s doesnt have as much of a yellow cast as the a7sii, so dialing down the white balance matrix settings Andrew provided (matrix not white balance) might make it warmer. Also if your using s-gmaut as a substitute on the a7s, use the V2 version for the a6500.

Was this shot mainly with 5600k (daylight) lighting? I'm assuming it was for using 7000k
