I have VX-III's on 90% of my guns,big Leupold fan for many years! A few years ago a friend of mine picked up a 3-9-40mm Conquest and I had a 3-9-40mm VX-III while deer hunting. It was getting late in the day when we saw deer in a small patch of pines,we both put the scopes on the deer and he said "all doe"! I coulden't tell with my scope so I looked through his. I was so suprised,I never thought in a million years there would be that much difference. Long story short,I bought 2 new scopes since then a 3-9-50mm and a 4.5-14-44mm and both are Zeiss Conquest...
