AF shooting is possible on most lenses using
all AF points with a maximum aperture value
of f/8
When using an extender on the EOS-1D X Mark II, AF is
possible using all 61 points even on most lens with a
total maximum aperture of f/8.
This combination of a lens with a maximum aperture
value of f/4 + Ext EF2x and a lens with a main maximum
aperture value of f/5.6 + Ext EF1.4x belongs in group H.
For example, AF focusing is possible even when shooting
with an EF2x extender attached to an EF 500mm F4L IS II
USM with a focal length of 1000mm, making extra line
return that is not needed.
