How do I set button to use only center AF point?
« on: March 03, 2013, 08:10:09 PM »
Hello, I just upgraded from an Xsi to a 6D.  Pretty excited, but I can't figure out how to focus as I did before.

I don't want to focus by half-pressing the shutter button.  Instead, I want to use only the center AF focus point by pressing that button on the top-right of the body.

I have a feeling I have to modify the C.Fn II setting, but am not sure how.

Any help would be appreciated!  Thanks!

Your 6D has something the Rebel lacked - an AF-ON button. That's normally used for back-button AF.  Go into Custom Controls (apologies if the 6D doesn't have that, but I'm pretty sure it does), set the shutter button to metering start, and the AF-ON button to metering+AF start.

Hi,
   For setting <AF-ON> button, look for it under [C.Fn III: Operation/Others]->[5. Custom Controls]
   For selection of center point as AF, press the <SET> button... you can only change AF-point if you are using Creative Zone mode (Av, Tv, B & etc).

   For details, look up in the manual.

   Have a nice day.

Thank you!  That helped me find the details in an online manual.  For some reason, it doesn't seem to be in my paper manual.  Anyway, I got it figured out so thanks.
