I'm not overly concerned with scope brightness for sheep hunting as I'm on top of the rocks and there seems to always be plenty of light. Been party to the harvesting of more than 30 mountain sheep and don't ever recall needing a brighter scope than a basic Leupold, but several times wished for a rifle and pack that weighed much, much less..........The Zeiss Conquest is a little brighter than some Leups but weighs 1/4 - 1/2 lb more..........to me this excess weight is unacceptable. The Leups while being a tad darker are still a tough, well respected non-fogging scope and work just fine on my sheep and goat rifles, while weighing several ounces less. I'm not a big fan of the Conquest lineup but do own several Victory Diavaris..........the real Zeiss. They are also just too heavy for a dedicated mountain/back pack rifle. They reside on rifles that get driven around, flown in and when off to places like Africa, or Mongolia, or Tajikistan.............
My goal in building this rifle was to have an adequate caliber/cartridge on a short action and have an overall package under 6 lbs. I was willing to compromise the quality of optics a little to achieve this goal. Not that a Leupold is really much of a compromise but the compact is not as bright nor as wide a F.O.V. but is the lightest 9 power scope on the market and is quite petite, and it does serve the purpose very well.
