I don't understand the problem... My 1DII doesn't show any AF point in AI Servo, black or red, when using the 45 focus point. So, having a black point is better than none right?
That's something I wanted to know. What about the other 1D cameras? How does it work?
This is the way I have it setup... If I activate the 45 focus point and set the camera to AI Servo, no AF point is visible.
When I want to track something I put the circle in the center of the viewfinder over my subject and press the AF-On button. At this point, still, no AF point showing.
Finally, while tracking the subject over the 45 AF points, no AF point is lighting up either...
Maybe there is some other way to display AF point in AI Servo in the custom functions but it never bothered me... In fact, I don't want my subject lighting up like a Christmas tree when I track it
