Over-sampling to avoid Bayer-pattern artifacts like aliasing and moire.  When I was using the 90-280 and SL, fine feather detail produced lots of both.  The a7rII's 42MP combined with the 280 APO still produces some but its much more manageable.  Some species of birds are more prone to Bayer-pattern artifacts and will produce such even with a camera with an AA filter, but 24MP w/o AA filter, an exceptionally sharp lens like the 90-280 and fine regular detail like many feathers is asking for trouble.
