Help with my D3100 AF-A problem

edited March 2012 Posted in » Nikon D3100 Forum
So when I'm in automatic mode, my AF-A setting won't work, but it works using the MF settings. I think it's broken or there is something in the settings that is wrong. Can you please help me guys. Thank you.


  • Howdy @nishmendoza - So if I understand correctly, you're shooting in Auto mode (mode dial is set to Auto) and AF-A is enabled as your focus mode. When you go to focus on a subject (half-press the shutter), the lens fails to autofocus? Which lens are you trying to use?
