Sony A7rii Extremely Poor Low Light Video

[scottdavis]

Hi There, 

 

I recently switched to the Sony A7rii from the Canon 6D.

 

I had heard wonderful things about Sony's low light video capabilities.  I know the Sony A7sii was better than the Sony A7rii, but I heard the the Sony A7rii was still pretty darn good in low light.

 

I am finding it about on par with a Canon rebel in terms of ISO noise. My footage become unusable at about 1600 ISO.

 

I have tried everything.  Shooting  35mm and full frame.  S-Log and not S-Log.  Nothing works.

 

So my question is this: Is this normal?  Is it possible I am doing something wrong?  Or just got a defective model?

 

Any help would be appreciated.
