4K Footage - XVAC-S S-Log2 From a Sony a7s and an Atoms Shogun

Today I received my Atomos Shogun 4K recorder/monitor and quickly set it up and shot a few seconds to test everything out. Below is the footage - first S-Log2 with no grading, then side by side, and finally full screen graded footage.

This is by no means a comprehensive review of S-log2 and the Sony a7s, I am merely sharing my first video testing.

Sony a7s Full-Frame 4K capable with external recorder like the Atomos Shogun

As most of you know S-Log2 is supposed to give you more dynamic range then Rec. 709. I've read some users claim excessive graininess or noise depending on how S-log2 is exposed.

I mostly eyeballed the exposure. These were +2 or more stops overexposed. I am going to delve deeper into this profile and experiment more closely to see what happens at different exposure settings.

Stay tuned...



I would like to be clear here, I have NOT been given any of these products in exchange for positive reviews. These products have all been purchased and payed for by me with no help from these manufacturers.
