>>3805691>Sounds like a you problem.It's a technical spec based on real requirements.
30 FPS at 120 AF sampling per second means each video frame will be analysed 4 times for each.
Think about it.
1 AF frame for reference.
1 AF frame +1 focus forward for analysis
1 AF frame +1 focus backwards for analysis
1 AF frame for final implementation.
This means you are guaranteed 0, ZERO Af pulsating ever, just 100% correct video focus in live recording.
There has been nothing like this before.
Even the A9 was only 3 samples per frame.
This is 4 samples per frame.
