i have the original non-IS with the R6
AF is slightly faster i feel on my 1DX, but obviously miss out on a lot of AF functionality.
Speed wise its very good, slightly behind my mk1 IS 400mm 2.8.
Panning side on or angle, no problem.
Subjects at a distance towards you no problem - you may encounter issues at closer distance but i cant say if the mk1 and mk2 are better but I would assume so.

Galah on approach, about a 50% crop of frame, run through LR+Topaz (r6+600mm

Nice capture And nice to see a fine old optic still working well.

Guessing from the outer part of one wing, electronic shutter used?

What are you getting at with the wing comment?
