#3. "RE: D5100 + Nikon AF-S 35/1.8G autofocus problems" In response to In response to 2
Thank you for the replies. However it is not accidental shifting of the focus ring that is the problem. I have made sure not to touch anything and to use the correct focus point, and the AF will still consistently set the focus slightly behind the subject when not using live view, only occasionally getting it right.
