Sony FX3 Base ISO for S-Log3, S-Cinetone & No Picture Profile

The Dual Base ISOs based on picture profiles for the Sony FX3

This is a quick cheat sheet for the base ISOs for the Sony FX3. If you're shooting in S-Log 3, you'll have access to Cine EI - which will take care of these values for you. I assigned my ISO (Custom button 3) to toggle between high and low base ISO, so I don't have to remember these ISO values off the top of my head. 

However, if you want to shoot in other profiles, like S-Cinetone, or not use Cine EI in S-Log 3 - here is a quick reference for the different Dual ISO values for the most popular profiles for the Sony FX3.

S-Log3 ISO
