I apologize if this is in the wrong section, but I couldn't find a help/faq section of the forums.
The other day I took out my camera (it had been properly stored in a camera bag with the lens cap on and everything secured) and started taking pictures, but I noticed that going through every single picture, about 2/3 of the way down, was a completely straight, horizontal line that abruptly stopped 1/3 of the way in. At first I believed it to be a scratch on the lens, however it still appeared when I put on my telephoto lens. I fear it may have something to do with the sensor itself, however the fact that it is a clearly visible, completely straight horizontal line makes me believe otherwise. I'm extremely meticulous about switching lenses, making sure to do it quickly and efficiently.
I also took out my memory card to see if that had anything to do with it, but the pictures STILL included the line in them. This is really worrying me, and I have no clue as to how it could have happened.

While by no means is this a good picture, the line showed up most prominently in it. It's not noticeable when in a very bright setting, but extremely prevalent on dark surfaces.
Any help would be extremely appreciated!
