A 3D-tracking
When the shutter-release button is pressed halfway, the colors in the
area surrounding the focus point are stored in the camera.
Consequently 3D-tracking may not produce the desired results with
subjects that are similar in color to the background or that occupy a
very small area of the frame.
A AF-S/AF-I Teleconverters
If 3D-tracking or auto-area AF is selected for AF-area mode when an
AF-S/AF-I teleconverter is used, single-point AF will automatically be
selected at combined apertures slower than f/5.6.
A Manual Focus
Single-point AF is automatically selected when manual focus is used.
