Hello - 
I'm new to the cinema line of cameras. I have a EOS R and 1DX Mii. 
The colors are very flat for me and I'm sure it's something that I am doing wrong. I have tried the REC709 straight out of camera as well as CLOG2 and then importing into Final Cut Pro X and applying the built in CLOG2 LUT. I downloaded the OWL C70 color profile to see if that would help and same result. 
I'm not very good at color correction but I tried to push up the saturation and just not getting the desired results.
Additionally, I'm getting more noise at 800 ISO than my 1DX Mii. 
I'm using a 24-105 RF L lens. 
Any pointers? Thanks in advance!
