In AI Servo AF, initial low-light reading from the instant that AF is first activated and AF calculation for the first shot are
improved — a new AF reading and control sequence gives the AF system a longer time to gather subject information,
without slowing camera responsiveness. No action or settings are required from the photographer to realize this benefit.

Low-light AF performance during AI Servo AF is
a key benefit of the new V. 2.0 firmware for the
EOS-1D X. Changes to the AF reading and
control sequence improve this for initial AF
readings and for the first shot in a sequence.
For subsequent shots in a high-speed,
continuous sequence, there's a new and

AI Servo AF 2nd image priority:
This setting has always allowed users to define performance during continuous, high-speed
shooting: prioritize sharpest possible AF, even if it means slowing the fps rate, or prioritize
shooting speed, even if it means an occasional soft frame is possible in a high-speed sequence.
