How can I tell if my camera is dying or the scene is just throwing off the camera? Like my example is I was trying to photograph some words on a grayish-olive green traffic light post, and my X-E1 most of the time underexpose the image at least by 2 to 2-1/2 stops. I was in auto mode and manual adjust exposure with the dial did nothing, as did changing aperture. I had to manually adjust shutter speed to get the right exposure. The sun was out, and I wasn't in the shade. I don't remember this happening before. Could this be a sign my X-E1 is slowing dying or due to the scene? Thank you.
