I am interested in buying a swarovski z6 2-12x50 and I noticed it did not have a parallax turret. I was told by the people(tech support) at Swarovski it was not nessasary for 12 power and under. Did I misunderstand? Is this correct? Both my Schmidt&Bender 3-12x50 and my Hensoldt 3-12x56 have parallax adj.
