Originally posted by ksignorini The K20D allows you to adjust your AF settings on a lens-type or all-lens basis. I understand that the K10D used to have this "available" as part of the debug mode...which has been disabled at 1.3.
I have three questions:
1. Can you downgrade 1.3 to 1.0 (or whatever version you need to use debug mode)?
Yes. See below for the steps:-

Yes!
Quote: 3. Is there any other way with the K10D to make the AF adjustments? After all, they are available in the K20D without sending the body away to service.
Yes! You can adjust the hardware screw settings which physically change the position of the AF module. But TRY AT YOUR OWN RISK:-
