interesting you can set a button to do more than 1 thing?
I did have my DOF button setup for ai servo to one shot.. but switched it over to * button. Love it... so doing sports i shoot away.. but if it is stand still stuff.. I can hold * and lock on to what i want...
also i couldnt get 65point af to lock on what i wanted it too in soccer so i set it up to the middle zone. much better.. but now i know next time if they are going left to right switch to left block so i can crop that way vs just everything being centered...
It is a nice function. Remember that you can also set up the buttons differently in the custom modes. For example, my DOF preview button is set for AI Servo - One Shot everywhere except in one custom mode (in my case mode 2) that I use exclusively for AI Servo wildlife shooting. In that mode I have the DOF Preview button set up to change my shooting mode.
