CineD explains why LUT support is so important:
If you own or use an FX 30, FX 3, FX 6, etc., then you can already load custom LUTs. Even some other Sony cameras offer this menu function, such as the vlogging ZV-E1 camera and the newish a7cII. Neither of the latter would be considered “Cinema” cameras by anyone. So it’s a little surprising that they would offer this functionality in some of their cameras, but not others – especially their flagship lowlight camera, the aS7III, which is used most by filmmakers.
