The lens is a Canon EF-S 18-55mm.
I recently dropped my camera from the tripod falling over while I was recording, now the camera won't AF and MF is very hard. It gets stuck easily when I try to MF it, and doesn't focus properly. I can zoom in or out, that is completely stuck. When I move the lens around I can hear a rolling noise inside it, like a marble. I had a fisheye conversion lens on it which I thought took the impact due to the paint ear on the edge it fell. I've read it costs about $200-$300 to fix this, and would prefer to fix it on my own. Does anyone know what the issue is so I can fix it?
