Naturally, we all adore the look of the Arri Alexa.

Does anyone know of the best Picture Profile to get close in-camera to the Arri Alexa's Log C?

I honestly favor the look of the ungraded Alexa over everything.

Thank you in advance!
 
The closest curve Sony has to the Log C cineon curve is Slog3 but that isn't available on A7s. Slog2 is the only Log profile available on A7s
 
Flaat is log and has accurate color, but is not suited for LUT workflows (no LUTs designed for Flaat AFAIK). I have no idea about how close it is to logc.
 
To get the Alexa look you need to get an Alexa...

Or at least have a camera with a very smooth highlight rolloff.
Therefore 8bit is just not enough because you need to stretch your footage
afterwards.

You can try to use SLog2 but be aware that you'll get surprises with color.
For SLog2 there's a LUT out there, called SLog2 to LC709 Type A LUT.
This emulates the Alexa look, but it's just the emulation and you'll still have
color problems with your A7s. Choose your color space carefully...

Here's some nice input:
