    Difference in Adjusting Parallax and Focus?

    While shooting at the range this morning, I had a discrepancy between my focus and my parallax. When I change ranges I always readjust the parallax. This normally adjusts the focus. I adjust the parallax by moving my head and adjusting until the target doesn't move. This was not so today. The target was blurry. When I focused, the target would move with head movement. Is this normal,its not normal for me. The scope is an SS 12X42 rear adjust. I have some of all powers in this line, but I didn't have another one with me to cross check. The problem was at one and two hundred yards. Just need some input before I call customer service. Could eye glasses have something to do with it? They haven't changed.

    First things first. Parallax adjustment is not all about focusing the target. Getting the target at better focused picture is by product of adjusting the parallax to put your reticle and sight picture on the same plane... blah blah blah blah... I'm sure you get the picture.

    I believe you are not the only one who's having the blurry picture problem when the parallax is adjusted accordingly. Has to to with my bad eye sight. I decided to compensate and pick the clearer picture over correct parallax. But, I have to make sure I am death straight behind the glass by making sure I'm not getting any uneven scope shadows and so on. Takes little time and experience, getting to know your scope, but after awhile you will know if you are straight behind the glass or now. It's either that or get myself a set of eye glasses which I really don't want to do for now.

    Exactly the answer I was looking for but I already wear glasses. Maybe they need an update. I FIRST TRIED TO ADJUST THE OCCULAR TO MAKE SURE THERE WAS NOT A PROBLEM WITH THE RETICAL FOCUS INTERACTING WITH THE PARALLAX. I'm not shouting, just hit the caps lock by mistake. I decided to go for the best parallax and aim at the sort of blur. Since I shoot several rifles, I would rather have to adjust to each scope, I have a hard enough time just getting my cheek weld right even with a good parallax adjustment. I haven't tried to adjust without glasses. I have to remove them for my spotting scope because of the eyepiece. I really really do need to solve this problem.
