Hello guys, so I have been facing problems trying to focus subjects that are far away on my 18-200mm at the 200mm end. The subject is around 100m away from my camera and i can't seem to get the subject in focus. Even when I manual focus I can't seem to get the subject at a distance in focus. I have done some test shots of different apertures on a tripod, the focus is at infinity but it still cannot focus on the subject, in this case the window close to the center of the frame. The image I get from the widest aperture is exactly how I see it through the view finder so it cannot be back focusing. Exif data is on flickr as well, Please advise. test shots-1 | Flickr - Photo Sharing!
