Quick question so that I don't have to do a test. If I shoot S-Log out to an external recorder can I record straight non S-Log to the SxS card? I kow I can record a LUT to the SxS, but I never tried to record non S-Log to the SxS while recording S-Log out.
He is asking if one can record non s-log to the card and s-log to an external at the same time. The answer is no. You can only record either a "lutted" s-log or regular s-log to the card while recording s-log to an external. You can't record, say, cinegamma to sxs card and s-log to an external at the same time.
...and that's only with the paid s-log upgrade (or the current RGB version of the camera).
If you're using the s-log picture profile with firmware version 1.4 - it's the same signal no matter where and how it's recorded. (someone check me if I'm wrong)
