agreed, the zeiss are a little below what they need to be... but not too bad for being 20 or so years old. i have never looked through the Zeiss 15x45, but can imgine they cn be lil iffy with the 45mm obj. the swaros are brighter in low light then the Duovids, but not enough to make a difference in a hunting situtation unless the buck is glassed up within shooting distance, but with most scopes having 40 mm obj, i doubt you would be able to shoot the deer/elk/what ever anyways. also, when i looked through Tylers Swaros, i noticed a white "haze" at the bottom of the glass at low light that was not present in the Duovids. for the bang for my buck, i am going with the duovvids... at 10 year wrranty on a demo pair of binos that cost less than the swaros is good enough for me! hell, within 10 years im sure there will be something leaps and bounds better!
