Your 500f/4 with the 2XIII behaves exactly as my 400 DO does with the 2XIII. Hopefully Canon will release a firmware update to address this as it seems like the camera is quite capable of focusing at f/8 in somce of your other tests.

Or just use a 1.4X Mark III in combination with a Kenko 1.4X TC to get an effective{/b] focal length multiplier of 2X with your f/4.0 lens, at least for the time being as a work around.
