I discovered that I cannot use more than 30 FPS and still have "Focus Track" features.  Focus Track is a key feature I use.

I have been using 1080P/30.
If I move to 4K/30 will there be any compromise in Focus Track performance...... or any other compromises?  I realize more data storage but other than that?
