DOES ANYBODY FIND THE FOCUS ( PARALLAX ADJUSTMENT) ON THE SIGHTRON SIII A BIT TOO SENSITIVE. I SEEM TO HAVE TO REFOCUS AFTER A CHANGE IN MAGNIFICATION. I DON'T FIND THIS WITH OTHER VARIABLE SCOPES aI USE.
This is a common problem with side-focus scopes, due to backlash in the gear mechanism. The front-focus system on the higher-end IORs doesn't suffer from this at all and is waaay superior!
