Lenses and Usable AF Points
Group A
Although the camera has 61 AF points, the number of usable AF
points and focusing patterns will differ depending on the lens. The
lenses are thereby classified into nine groups from A to I.
When using a lens in Groups F to H, fewer AF points will be usable.
See which group each lens belongs to on pages 105-108.

which group the lens in use belongs to.
When you press the <S> button, the AF points indicated by the mark
will blink. (The / / AF points will stay lit.) Regarding lighting up or
blinking of the AF points, see page 94.
Regarding new lenses marketed after the EOS 5DS/EOS 5DS R Mark III
(in the first half of 2015), check the Canon Web site to see which group
they belong to.
Some lenses may not be available in certain countries or regions.
