IIRC, the Optisan CP was developed with UK field target shooters — for competitions where you are not allowed tomakechanges to the scope when the match begins.
It has therefore a long range where the parallax error is negligible and sharpness is good — what I call the Parallax and Sharpness Range — PSR (in photography, the depth of field, a bit of an ambiguous term....).
That's why the objective lens is only 32mm (most common is 44..).
The field of view FoV is also quite large — 36y @100y for 3x.
I might have bought it already — but I can't stand capped turrets — the manufacturers' clear measage to "set the turrets and then leave them d#ng thangs alone!"
