I have a Nikon D3300 DSLR with 18-55mm lens. It was working well, but yesterday fell from the tripod. Now, I am trying to take pictures, but it just says the subject is too dark and can't adjust the exposure even when shooting in bright daylight. It just shows a completely black image on the screen, but my previous pictures and videos from before the fall look okay.
What should I do? Is the problem with the camera body or lens? Should I buy a new lens?
