I posted this on another hunting site:
I was very surprised at the Vortex 15x56 Kaibabs and how sharp they were. Until we looked at the resolution chart, one could hardly tell a difference between the three binos by looking a clusters of pine needles on a distant tree about 100 yards away. While jumping from one bino to the other, once I would prefer the Leica 10+15x50 Duovids and the next time the Swaro 15x56. Another viewer preferred the Swaro, and a third preferred the Leicas. The main difference was the bluish cast of the Swaro which some may prefer and others wanting a more neutral tone offered by the Leicas and Vortex. The Vortex had equal contrast and brightness withe the Swaros and Leicas. As Dennis noted with the resolution chart, the Swaro was about 1/2 block better than the Leicas, and the Vortex was about one full block behind the Leica. looking at the edge of a skylined tree trunk, all had the same amount of a greenish color fringe to my eyes. The Kaibabs also held sharpness to the edge the same amount as the Swaros and Leicas. The Kaibab's lens tubes could be folded closer together than the Swaros or Leicas (a consideration for those with closely set eyes), but the eyecups themselve were larger in diameter that those of the Swaros and Leicas. For $1200, the Kaibabs are a best buy for 15x binos, imo.
