OK. EVERYBODY that has a Sightron Blue Sky II put it in the refrigerator for one hour. Take it out and see how stiff the focus Is. Try the focus before and after you put it in the refrigerator. A refrigerator is about 40 degrees so this should be a good test. I am still keeping the Sightron. It's too good optically and it is light. I am going to sit here while I watch TV and rotate the focus for an hour and see if it loosens up. HaHa!
Well I did it and mine are a tad bit harder to turn, but I can manage it with one finger (index) no problem! Maybe you guys are just weak!
