I've noticed the exact same with the focus wheel. And yeah, I was able to set the right eye diopter but then when I move to something farther/closer, it once again, feels slightly out of focus.I had the conquest 15's and found the focus wheel to be very finicky. Just a tiny bit of wheel movement would bump them completely out of focus. They were usable but I ended up going with the swaros for better CA control. Were you able to set your right eye diopter? You can always send them into zeiss for inspection if you feel something might not be right.
