AF results from active communication between lens and body. Canon has a history of including in their lenses some technology that supports technology that ison teh drawing board for future body releases, so I would not be surprised if the new 400 f2.8 or the 6000 f4 mkiii will work better with the EOS-R than the 500mkii does.
But where does this leave the DO lenses?
The excellent 400 f4 DO weighs 2.1kg. The 600 f4mkiii is under 3kg (lighter than the 500 mk ii) so how much weight can they save with DO technology?
