I have this D3300 that was working completely fine.
Someone was playing with the settings and I realized that I cannot focus on objects anymore.
I don't think that there is something physically wrong with the lens, but most probably with the settings.
When I choose MF (manual focus) from the camera's shortcut settings panel, I can see that the focus area mode is disabled when it is in MF mode. Also when AF is active, I still get very blurry images, just like if the focus mechanism is disabled or so since I can't hear the focus motor in my lens anymore.. What could have gone wrong?
