I believe Kahles and Swarovski are owned by the same parent company, but all Kahles optics are designed and built in the Kahles parent plant in Vienna, Austria. The companies operate completely independent of each other.
It has been said that in parts of Europe the Kahles is the premium scope and Swarovski is the working mans scope.
I have never owned a Kahles. I have had a couple of Swaroski scopes and have a pair of 10x42 SLC binos now, if the Kahles are better or even equal, then that says a [beeep] of lot to me!! I think you have a great quaility scope!
