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.
