I’m putting these notes here for my own reference. I will add to them as I find new things to remember. They may help others too. As I already have a Sony FX9 and an FX6 I thought it would be a good idea to have some notes about some of the difference I need to remember when using an FX3 (and A7SIII) alongside the FX6 or FX9.
BASE ISO:
Gamma/Base ISO | S-Cinetone Low Base | S-Cinetone Hi Base | S-Log3 Low Base | S-Log3 High Base |
FX3/A7SIII | 100 | 2,000 | 640 | 12,800 |
FX6 | 320 | 5,000 | 800 | 12,800 |
FX9 | 320 | 1,600 | 800 | 4000 |
ISO RATING:
The FX3/A7SIII ISO ratings are just over 1 stop brighter than the same ratings on the FX6/FX9 except when using S-Log3 which matches correctly. So if using 320ISO for S-Cinetone on the FX6/FX9 use 100ISO on the FX3/A7SIII for the same brightness of recording.
HDMI:
To use both the HDMI out and the camera’s LCD screen at the same time you have to turn off the HDMI Info in the External Output settings.
STABILISATION:
To use post production stabilisation you must turn off Steadyshot in the menu.
XAVC-S-I Codec has the same bit rates and appears to be the same quality as XAVC-I.
APPLICATION:
FX3 Uses “Imaging Edge” app and FX6/FX9 use “Content Browser Mobile” app.
EXTERNAL POWER:
The FX3 can be powered externally via the USB-C port. With a compatible USB-PD power source the camera can be run continuously.
