Viewfinder (VF) Specs.
The camera’s viewfinder (VF) is a 720p Rec.709 screen.
Slog 3 images look low contrast in this screen unless a LUT is applied.
The VF cannot show all the highlight detail in uncorrected Slog 3
images.
You need to apply a LUT and “normalize” the image to see the highlight
details inside the Rec.709 colour space. See the section on Cine EI
Shooting Mode.
