D4. Camera working perfect. I did some video with live view and messed with menu. The focus light turned green like it's supposed to. I went back to taking pictures. My red light does not turn green when in focus through viewfinder. The pictures seems in focus, and I can see it focusing. In live view the light will turn green on screen, as it is supposed to, but not through the viewfinder. I changed lenses with no difference. Still no green light when in focus. Any ideas? Thanks.
