Having worked as a photographer, it seems that parallax has a slightly different meaning when it comes to scopes. I've done a lot of reading about rifle optics over the past couple of months, but haven't seen the "moving crosshairs" problem explained so succinctly. Thanks. So when a scope is described as "parallax-free at X yards," that means that at X yards and beyond, the crosshairs won't appear to move when you move your eye?
