It says lenses before R5 may require firmware upgrade or not supported?????

For coordinated control. So, perhaps you'll only get 5 stops of IS on some lenses. Big deal.

The way it reads is that "In-body IS up to 8 Stops" is not supported on some really pricey lenses. The default statement is "up to 8 stops" for all of them. The default statement doesn't imply you get 8 stops anyway, so what exactly is "not supported" on that list of lenses. Coordinated IS?  If you only get 5 stops, that is covered by saying "up to 8 stops".  It would be very different if they said "8 stops", but they said "up to 8 stops".  That is some very muddy wording.
