EOS-1D X 61-Point High-Density Reticular AF Cross-type Points
61-point AF (2) The number and placement of cross-type points used by the f/4 lenses
EF70-200mm f/4L IS USM
41-point cross-type AF points can be used
In Group C, 41-point cross-type AF points can
be used with lenses having an f/4 maximum
aperture (or f/2.8 maximum aperture lenses
using the EF 1.4x Extenders). Of these, the 20
points on the left and right are f/4 and f/5.6
Group C
41-point cross-type AF points available,
and they can be used with a high level
of tracking performance
AF focusing is possible with all 61 points.
All AF area selection modes are available.
