So recently I got a Nikon D3100 DSLR.
It was focusing fine and everything until one day where everything suddenly got really blurry no matter what I did. If I zoomed or unzoomed, everything got blurry. If I stood far away, it was still blurry. I didn't really mess with it other than turn the dial to change its modes (i.e. Auto/Manual/Portrait/Sport/etc.)
How can I get it to focus and sharpen pictures again?
Added (1). Also, while normally you can get pics where the subject is sharpened but the background is blurred out, now it's like the opposite.
My friend set it to Manual when she used it a day before this happened. (Maybe this is why? I'm just not sure)
