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.
|Gamma/Base ISO||S-Cinetone Low Base||S-Cinetone Hi Base||S-Log3 Low Base||S-Log3 High Base|
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.
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.
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.
FX3 Uses “Imaging Edge” app and FX6/FX9 use “Content Browser Mobile” app.
The FX3 can be powered externally via the USB-C port. With a compatible USB-PD power source the camera can be run continuously.
