Having done a Arri Amira vs Sony FS7 test ( https://vimeo.com/153091201 ) I had a lot of nice feedback and people asking me if I could do the same thing for the Sony A7s. And so... I did :-)
I wanted to see how well the Sony A7s can match the Arri Amira, which is known for its nice color rendition.
Like the Sony Fs7, I saw that the a7s has a more purple/magenta/blue tone while the Amira has more yellow/green.
The provided lut by Sony, LC709A, to emulate the Amira makes it even more magenta Therefore it doesn't match well with the Amira in preset white balance using the Arri c to rec 709 LUT. It also has more contrast, which makes it a "harder" look. To my opinion, all of the above is exactly why some people find the Sony look too "video".
Having tweaked the footage in Davince Resolve I received a much closer match to the Amira.
You can get them close. Close enough to be able to combine them for a multicamshoot.
The Sony a7s is a nice camera, with a lot of dynamic range for a 8 bit camera. Incredible low light capabilities, but when shooting Slog2 (at native 3200 ISO) I saw more noise then I would like. Exactly why most people overexpose the slog2 by 1 or even 2 stops. And... I would also advice to do so.
As I invested quite a lot of time in this, I am willing to share my LUT for a small donation in return.
You can now download the LUTs, using Gumroad...
