I have used the 3.5X10 Conquest on my 7mm for the past couple of seasons and it held up to the harsh winters much better than the Leupold that preceded it. I thought the Leoupld was great till I put this one on and dealt with some bitter teperatures. It never fogged up on me once and I shot my deer last year at last light. I probably wouldn't have had the samebrightness with my old scope. My vote is for the Zeiss, you won't be disappointed.
