Has anyone ever tried this? I purposely defocused the scope so that the in- focus point was in front of the target (a resolution chart). I took pictures in focus mode Infinity, Macro, and Auto Focus. All images were equally fuzzy. I repeated the test defocusing the scope so that the in-focus point would be beyond the target (very fuzzy to the eye). I took the same sequence of pictures. At Infinity setting, the image was fuzzy. At Macro and Auto Focus settings, the image was completely sharp.
I am guessing that the camera can only adjust focus one way; the other way the lens is already racked out to the infinity position and no more correction is available. I am now trying to see if this is a viable way to guarantee in-focus pictures all the time. Is it possible that those of us who have trouble getting in-focus pictures are really adjusting the scope in a way that the camera cannot compensate (maybe due to the nature of our eyes)?
I am using a Nikon P5100 and a Swarovski 65 HD.

Have you observed at which distance the camera think it is?
Does the camera think the object is very close or that the object is located close to infinity?
