[QUOTE="Hue, post: 826854, member: 54665"] Hello to everyone. This is my first post. I joined after reading a lengthy thread by ?D200 who is seems hasn't been active in a while. I have a focus problem that my D810 has been to a Nikon service center for 3 times and they state they cannot reproduce... even though the problem is visible every single use. In any autofocus mode the camera focuses and returns a sharp image. However, the image in the optical viewfinder is not in focus. It is not a diopter issue. If I'm using a lens that allows manual focus tuning while in autofocus mode I can autofocus and then fine tune to achieve a sharp image in the viewfinder. If I shoot then my resulting image is well out of focus. Again, though, if I simply allow the camera to focus and I shoot then I get a great image. If I change completely to manual focus I get the same. Sharp image in the viewfinder but out of focus results. I have found that I can manually focus to a sharp image and then move the focus ring between maybe 1/8" and 1/4" toward closer and I get a sharp image... out of focus now in the viewfinder. I have read about adjusting the focus using the screws under the bottom plate but I hesitate to do that since it seems to be focusing fine. I'm sure there is an adjustment to fix this but I'm not sure where to find it. Can anyone help? Also... it's the same with any lens I use. Thanks [/QUOTE]
