My nikon d80 can't change focus areas in
You have locked on to the af-l and it won't default. There are a couple things you can do, where is the book? I can try to explain it, but,,,, In the menu, go to the pencil logo, 03, AF area mode, Dynamic mode, your multi selector button should go round to the 5 points in the view finder. Now the focus lock, when the picture is in focus, it will be in the view finder as a circle with ( ) around it, with the shutter button held down half way, hit the AE-L, AF-L button. it will remain locked, Go back to the menu, pick the pencil again, select the AE, AF lock, and go through the menu there to default your settings, or see if it is locked on, or change the settings, I have mine on auto and hold, the single ones, af ae are off. Now that I am totally confused, you must be too. Hope this works.
