Same here on recently purchasing the camera. I have until the 24th to really know the ins and outs of this camera. I am shooting a feature length narrative (my own project) and testing everything prior is essential for me. I didn't know until two days ago that the quality degrades slightly, especially after seeing that chart. Others made it seem like the image got really bad when shot in 480 fps I believe? Now I know it's no longer HD at that point, but getting more aliasing is an issue for me, at 120 and 240. I suppose in a way you just need to find the right setting for what you do and know your imitations. I think someone posted on here in another post, that all the cinematographers didn't just find the magical shot - they tested, tested, tested and I feel that is so crucial.
When it comes to PP settings, I understand it but not to the point where I know what "knee" is, etc. I'm still learning. Knowledge truly is power at this point.
