Hi there folks. I'm having a problem with my D200. The far highlight points (city lights at the horizon) seem over-sharpened by the camera. Them have a square, pixelated appearence. When the points are large, using a small aperture I can get them to become star-shaped, what is nice and avoid this problem. But with large apertures and smaller highlight points I have this pixelation problem. Is someone else experiencing this? When I got the camera I tested it for banding and couldn't make it to show any banding. I concluded that it was same in that regard. Anyway, this seem to me like a 'residue' from a banding problem. I don't know if there is a way to resolve the problem but I am just curious to know if anyone else noticed this. Cheers.
