Ever since the lens flare challenge my images that taken in the suns direction have a "fog" spot. (The sun doesn't have to be in the image) The spot is in the same location on the images whether I take a vertical or horizontal picture but they don't appear if the image is taken with the sun at my back. I have heard that the sun can damage your sensor and I am wondering if this a sign of the damage. Has anyone else had these issues?

Thanks.

Have you tried it with a different lens, to see if it is the lens or the camera?

I haven't had a problem, and I took a huge amount of pictures for the sun in frame...

Ambaker had a good question: is it with all lenses?

It is with both my 18-200 and my 80-400. I haven't tried my fisheye yet but I will tomorrow. It seems like it is the camera but I will test the lenses again.
Thanks!

Take a good look at the sensor by reflecting a bright light off of it. If it's physical, you would probably see it. A magnifying glass helps with doing this. Hopefully it's just a smudge on the uv filter over the sensor, and can be cleaned off. Look on the opposite side from where the problem appears in your photos.
I certainly hope that you haven't done any permanent damage. A lens, esp a wide angle or fisheye, concentrates the sun's rays on a very tiny spot on the sensor, including the infra red rays of heat.
Other forums say that it takes a long or fast lens to cause a burn. I would also try to get a look at the shutter if the sensor looks good. A spot formed by direct sun rays can focus on the shutter and burn it.
