"D5100 malfunctioning - black rectangle appears in photos"
Many new years memories were made last night, unfortunately very few documented since after midnight, my camera started to show that photos were showing up with a large black rectangle over 7/8 of the picture. After swapping lenses, it appears to be the camera that has the problem, and a look inside doesn't show any immediate difference. I'll be taking it to the shop tomorrow anyway, but I'm so worried and wanted to know if anyone had any ideas of what this might be and how serious it is? Thanks!
