Low-contrast subjects
(Example: Blue sky, solid-color walls, etc.)

(Example: Car with a reflective body, etc.)
Near and far subjects covered by an AF point
(Example: Animal
in a cage, etc.)
Repetitive patterns
(Example: Skyscraper windows, computer keyboards, etc.)
In such cases, do one of the following:

the lens is f/5.6 or smaller (larger f/number), AF will not be possible
(except Live mode/~ Live mode AF). For details, see the Extender's
instruction manual.
