I was on walkabout with my XE2 yesterday. As is my normal custom: the camera was switched off, my XF 18-55mm F2.8-4 zoom lens was mounted with the lens cap off, camera was hanging at chest level from the neck strap. A couple of times, as I switched the camera on and brought it up to my eye and I noticed the EVF was totally white at first, but gradually came into the expected view within 2 or 3 seconds. I had not noticed this behavior before. Problem? Explanation?
