Haha yea I fully understand the whole "sharpness" thing and I'm wondering if that is something a colourist can fix? I have seen some footage from the 4.6k that looks very clean and I honestly think a lot of it does come down to the grade.
The only video with any form of filtration was the "autumn" one which had a Hoya IR Cut and a SLR Magic Vari ND. That video was shot wide open at F4 on a Canon EF 24-105mm lens so there was quite a bit of ND happening especially at ISO 800.
I actually did a video test comparing the SLR Magic Vari ND to the Hoya ProND on the 4.6k at 4:1 raw but I haven't uploaded it online. It was actually very difficult for me to see the difference in the 2 ND's so the Vari ND seems to be pretty good. I also compared 1080p ProRes HQ to Raw 4:1, and once again, the change in "look" appeared to be very slight although I do think that the 4.6k raw stuff did look a lot more "natural".
The worst video was probably the "Bubbles" one since I was shooting handheld with a Rokinon 14mm at 800 ISO at probably like a T8- T16. When I graded it in colour it looked really bad and it felt like I needed an IR cut or something, that's why it is in B & W. I shot this very quick video on the same day (all audio was literally scratch audio from the camera):
I have had to shoot a number of very quick videos (one day turn arounds) at my job and so it has taught me how to grade the footage pretty fast:
