thanks for that info, the pa thing was something Jon said in my Discovering parallax thread:
"Of the 7 attempts at getting a useable 80 they all had pa error which really showed up locked in a vice. Different model the 10-60 even on lowest 10 mag totally out of focus, pa eror is absolutely minimal. Deon ship them out set at 0D, to most that means having to wind eye bell ret focus in approx. 1 3/4 revs, also come optically centred".
I did ask about it but didnt want to push the point.
I love it, hope they never change the killzone standard sizes
