Great test, macgregor. As always.
The Amira highlights are just perfect. The a7s suffers a bit there, but it sees a bit more into the shadows and seems a bit sharper (well, the Amira was stuck at 2K...). Much closer than most people would expect, in any case.
How did you expose the a7s? Folowing Sony's suggestions, or with a slight overexpose?

Here's two Doritos Superbowl contest entries shot on the A7S. Ashley Maddox DP'd.

Was the frame rate 30P Finbo?

When you say "avoid sgamut" when using SLOG2 - what color profile did you settle on?

I use cinema, with some tweaks
but really, just using cinema would be a great improvement over sgamut2 if you ask me (sgamut works if you're using a LUT-based workflow, for everything else it's horrible)

Thank you for the reply and the link. I will test those settings. I think originally I had avoided coupling SLog2 with any color profile other than Sgamut because I thought I read somewhere that to achieve 14 stops of DR from the camera you needed to stay locked to SLog2 + Sgamut and stay right at 3200 - and that any deviation eliminated (at least somewhat) the 14 stops of DR.

You have to stay at slog2 and 3200 to get maximum DR (which is impressive but way short of 14 stops, btw). I haven't seen any effect on DR from changing the color profile.

I think you mean cine gamma with gamut color (and no LUT in post)
I use slog2 because it has slightly higher DR than cine4 with has clearly higher DR than any other gamma profile. If you don't want to deal with the ISO 3200 limitation, cine4 is not awful by any means.
sgamut is awful no matter what gamma you pair it with (the only way to make it work is by using official LUTs in post, which will deal with the color nonlinearities and "fix" the problem)

Thanks Joost. Two in a row! Although I think I just squeaked by on this one. I am going to step it up on the next one... Or at least I am going to try

Your link seems to measure only subjective "useable DR" not absolute DR from white clip to noise floor. From what I've seen it is possible to see 14 stops from white clip to noise floor. If you measure to an arbitrary and subjective noise level you will get arbitrary and subjective measurements.

Really great work. I'm new to the forum but I've caught a few of your videos via Vimeo. Would you mind sharing a bit about how you capture, sort, and edit audio in your videos? More your creative approach to it rather than technical. Thanks!
