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
With the exception of a small group of lenses
(groups F and G), almost all lenses that have a
maximum aperture of f/4 or greater are
included in Group E, and can use the 21-point
cross-type AF providing even higher precision
focus in these areas than with previous cameras.
Some macro lenses with a maximum aperture
of f/2.8 are also included.
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.

of tracking performance
Group E
The central 21-point cross-type
AF can be used
On the EOS 5D Mark III equipped with a full size sensor, an extender is often used for sports
photography etc. where longer focal lengths are required. When many large aperture
telephoto lenses (200 - 400 mm f/2.8 class) are used with the Extender EF 1.4x attached, the
maximum aperture will become f/4 and these combinations therefore are included in Group C.
High performance AF can be utilized with the 41-point cross-point AF Therefore, offering new
possibilities to use an extender.
Many f/2.8 maximum aperture lenses using a 1.4x extender can utilize 41-point AF
f/2.8 and f/5.6 cross-type AF
