I also have the Swarovski Z5 3.5-18x44 scope. The glass is outstanding. Elevation turret is limited to one revolution, which equates to 13.25 MOA. To do over again I would purchase the X5 5-25-50
I have the Z5 3.5x18-44. Light transmission is outstanding. I shot a four point Whitetail at 135 yards 28 minutes after sunset. That is two minutes before legal shooting cut off time in Washington. I had no problem putting the crosshairs on his vitals.
