After the previous firmware update in March, that supposed to be an upgrade to Log color profile for the P4P, I used that profile for the first time - Log profile with 500 locked ISO - with the appropriate ND filters for proper exposure and I noticed big amount of banding at the Blue Skies that made the footage almost unusable without heavy editing and deband techniques. I never noticed such a banding when I was filming in Cinelike profile at the past. I used the polar pro shutter line nd filters. Do anyone of you notice the same problem?
