Capability of f/8 supported AF points
When using an extender and a maximum 
aperture of f/8, all 61 AF points and AF area 
selection mode can be fully utilized on most 
lenses.
As indicated in the chart on P. 92 "Group F (f/8 
supported AF points," with the combination of most 
lenses and extenders that total a maximum aperture of 
f/8, AF is possible with all AF points. In addition, in this 
case the AF area selection modes such as auto selection 
AF and Zone AF can all be used. Therefore, it is effective 
when using a combination of Lens Extender EF 2x with a 
lens with a maximum aperture of f/4, or Lens Extender 
EF1.4x with a lens with a maximum aperture of f/5.6. 
Utilizing an extender is recommended when you want to 
do telephoto shooting with your existing lenses.

combinations of lenses with f/8 supported AF points and extenders.
