Use SOS, NVS, TWS, TWS MG, Nightstalker, RCO (scope), ARCO (scope), MRCO (scope).
Toggle "zoom out" (2 x Num - by default) then go optics (secondary mouse button by default) then "go out" optics (SMB again) and you found yourself in "zoom in" toggled. Now try from "zoom in" and find yourself in "zoom in" again. Other sights returns you in no zoom position. I guess you may want to make all sights return to no zoom position after use, but i think it would be better if using sights will not affect zoom state at all.
Now i realise that my english need more practice :)
