Tomorrow I am gonna do some shooting with the Olympus 12mm and set to its hyperlocal distance. Hope this setting can solve the problems we are now facing when shooting videos.
A technical quibble; the term "hyperfocal distance" has a very specific meaning.
It is defined as "the distance between a camera lens and the closest object that is in focus when the lens is focused at infinity.".
Thus, you would not "set it to its hyperfocal distance"; you would instead "set it to infinity focus", then see whether objects around the hyperfocal distance are in focus.
