61-point AF (2)

The number and placement of
cross-type points when using
f/4 lenses
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 many
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 cross-type AF providing even higher
precision focusing in these areas than with previous
cameras. Some macro lenses with a maximum aperture
of f/2.8 are also included.
