D600 Unexpected AF Priority setting behavior
Thanks for checking. I just re-tested my D600, and it does not behave the way I originally described. I must have done something wrong. Sorry about that! I wish I could delete my original post.
So in AF-A mode, if it decides to use AF-S, it defaults to focus priority, and if it decides to use AF-C, it defaults to release priority?
That would be a convenient way to quickly change from release to focus priority for when I need to hand my camera to someone else to take a picture for me.
I have just tested my D600, and it does take a photo as soon as I press the shutter release in AF-C regardless of whether the camera has achieved focus or not.
Have you checked your Custom settings a1 (for AF-C) and a2 (for AF-S), because with these you are able to set whether you want the camera to be on shutter or focus release.
However in AF-A it will allways be focus release priority - unless I have missed a custom setting somewhere.
