[QUOTE="bruce_ventura, post: 933403, member: 34084"] Conquests and Conquest HDs use simple doublet objective lenses, like most other scopes below about a $1,500 price point, so don't expect a big difference in resolution. Otherwise, Zeiss optics are quite good. Stray light management is good and image contrast is high. Zeiss lens coatings are quite good as well. Sightron optics are made by Kenko and use Kenko lens and coating technology. SII and SIII lens coatings have relatively low transmission in the blue, which degrades nighttime performance. Leupold VX-3 and Mark 4 variable power scopes have a blue-enhanced lens coating (XT). Sightron external lens coatings are also softer than the Leupold external DiamondCoat2 coatings. Also, SII and SIII scopes do not have good stray light management, and image contrast is average at best. Between Sightron and Leupold, my vote for a hunting scope still goes to Leupold. Yes, the nearest Leupold model will cost more. That extra cost comes from American labor, no questions asked warranty, and better designs and coatings. Actually, I'm not a big fan of Leupold, but they do know how to build scopes. Regarding low-light performance in general, the biggest factors determining perceived brightness are exit pupil and magnification. Differences between lens coatings usually have a smaller effect, and differences between lens materials have almost no effect. Paul, When doing side-by-side tests in low light, I've found that it is not easy to insure that both scopes are set to the same exit pupil size and magnification. You would have to share the details of your side-by-side comparison for me to understand why the Leupold lost. [/QUOTE]
