Now, I am not quite sure what the 709tone Base look exactly is and Sony doesn’t provide any direct documentation describing exactly what it is or what it is designed to do.

What I did find is a reference to 709 Tone/Color in a Japanese technical document that was discussing S-Gamut and S-Log2/S-Log3. To me it looks like the new 709tone Base is probably very similar to the old LC-709 look profile that you could use in the F5/F55.

Just to be crystal clear, the 709tone Base is a picture profile just like S-Cinetone. It is a standard Rec.709 picture profile that you record when you want a baked in look. It isn’t a LUT and you can’t use it when shooting S-Log3.

The LC-709, LC-709TypeA look profiles were designed to provide low contrast with broadcast color. That is what I believe the 709tone Base is similar to as they are more suited to broadcast environments. S-Cinetone is a higher contrast picture profile just like previous Cine+709.
