Vortex 10x42 uhd - Vortex Razor UHD 10x42mm Ablb-Koenig Prism Binoculars

These are beautiful: very bright thanks to the A-K prisms; handsome, strongly built. The images are sharp and clear, with natural color. There is a slight, barely noticeable chromatic aberration, manifesting as green and purple color fringing on opposite sides of back-lit vertical surfaces, and the tiniest bit of pin-cushioning, for which reasons I'm rating these as four rather than five stars; however, these flaws are so slight that they are not seriously distracting, and can be ignored after a while. I found that they nearly disappear with the eye cups all the way down. The focus knob is very smooth and clean, and the diopter is very good. The binos are heavy, again due to the A-K prisms and the extra length required to accommodate them, but for me the weight seems to drop away after a short time and they become quite comfortable. They are not, however, for one-handed use. The carrying case, although well-made, is at least a full inch too short and hence fails to cover the binos completely. Recommended for backyard bird watchers and hunters who use tripods. Hunters and other outdoorsmen might consider buying a better-fitting case.
