I have been attempting to use the AF-ON button instead of the shutter button for focusing. I went to the Custom Setting Menu at a5 for autofocus activation and pressed AF-ON only. Well, the camera focused with the AF-ON button, but when I took a shot and pressed the shutter button half way down everything went out of focus. I don't know what I did wrong. Do I have to set the auto focus to af priority as an additional custom change? Your help will be greatly appreciated. Thanks.
