I own two Nikon D7100s, and right now the exposure indicators are off for both of them. They display a level of exposure, but it's not accurate. For instance, shooting in manual, with a Nikkor 18-105mm DX lens, at a shutter speed of 1/13s, f/4, I should be getting tons of overexposure. Instead, the meter is at 0, with no overexposure in the picture.
It's doing this for both cameras, where the exposure indicator doesn't match what the picture should look like. I've checked throughout the settings of the camera, and can't find anything in particular to correct this. Any ideas?
