Light gathering in M43 vs FF

I read your explanation in post 3, and it still has me confused as to your purpose.  Why does light gathering matter for sports/wildlife DOF - particularly the concept of whether m43 DOF/subject isolation is sufficient for those purposes?

In these forums language can frequently be a barrier to effective communication, and the phrasing of the original question may be confusing people.
