A D3200 was and is my second digital camera. They do pretty well. They are still some better in low light than my Original digital D60 NIkon.
It was commented about the auto focus not locking in on a still subject a park bench, and one thing I know is when in low light they have trouble auto focusing. If the light is low enough, and or the area where your AF setting is set to is very dark, and you’re set on a single point focus setting it will keep trying to catch the right focus and move in and out, and some times after a minute or more it might lock on, but wouldn’t depend on it. Glad you found one option to set to AE-L. I like to manually focus in those instances but that can be hit or miss in low light also, unless you have really good eyes. Thanks for informing me of the AE-L remedy. Hope is helps a little.
