I've read through others posts and, based on the suggestions, I have eliminated the batteries, lenses and SD cards as the reason. In recent days, as I reviewed my photos the camera would get stuck on one photo. Turning the camera off did nothing, I had to remove the battery to get it to shut off. This happened a few times. Yesterday upon reviewing photos, the camera shut off and will not turn back on, regardless of what I do.
Any ideas? I'm guessing the body is fubar.
