I'm not sure if this topic was already covered. I found nothing using the search box.

Is there a way to hack tho focus acceleration slope such that the speed at which we handle the focus ring doesn't matter? Turning 90 degree in one direction slowly then reverting to the initial position at a greater speed, do not put you back at the same focusing distance (which is normal with this acceleration behavior.)

This is a problem when wanting to control the focus from an external motor (putting a step motor to turn the focus ring at predefined distance for instance).

So, I'm wondering if it is possible to cancel this behavior, such that 'n' steps on the focus ring always produce the same update, at whatever speed we moved it.
