Not even all of Sony's own native E-Mount lens line(only a selection of their most recent ones) take full advantage of the 20fps burst mode in their new flagship.

Why is that? Is it because the amount of time between frames is too small for the older lenses' autofocus systems to work?

Yes, I believe so. Essentially, if the lens and aperture mechanisms were not designed to complete each cycle of operations in less than 50 milliseconds, then the lens can't necessarily keep up with the demands of 20fps.

I think we can assume that Sony have had those requirements in mind for a number of their recent designs, and particularly the higher end ones, but not necessarily for lenses issued some years ago.
