I had a funny thing happen with my Leupold VX-1 2x7 scope the other day at the range. Since deer season is fast approaching I took out three rifles to shoot and make sure the scopes were still on. The other two rifles are equipped with the older Nikon Monarch UCC scopes,one in 3x9x40 and the other 2x7x32. Both are superb scopes. Of course since both use those fast focus eye pieces you almost always have to turn the thing to get a crisp focus at the paper target that is 100 yards away. No problems both scopes were dead on. Then came my turn with the VX-1. For the life of me I could not get a sharp focus at all. I actually had to use my reading glasses to focus clearly on the target and shoot. Is this my scope and it needs to go back or me?? This scope has always been bright and clear with no focus issues at all. Hard to believe from one year to the next something like this could occur. Again my Monarchs were crystal clear in focus resolution. It is 10 years old and has never been hard handled,in other words dropped,banged into something etc. If it is the scope what causes this?? In my life I had a new 3x9 Denver Redfield break a reticle after a very hard fall due to ice and I had another straight 6 power Redfield that clouded up but that scope was close to 35 years old.
