The majority of lenses can make use of the
central 21-point cross-type AF
With the exception of a small group of lenses (groups G
and H), almost all lenses that have a maximum aperture
up to f/5.6 are included in Group F, and can use the
21-point cross-type AF (f/5.6 cross-type) in the central
area. Many f/2.8 maximum aperture large aperture
telephoto lenses when used with the various EF 2x
Extenders will fit into this group.
