Well, I don’t point the camera directly at the sun, usually offset to the photographic 1/3 rd . Ok with a film camera, but, never had a problem with digital Canon 5D mark II including video in 5 years.
But, I have noticed a light image retention using 3ccd Panasonics, but, no lasting effects on the image sensor, TAKE CARE !
