The 10x34 Passion SD Binoculars from GPO USA are strong enough to reveal distant architectural details or natural landmarks, yet can focus less than 10 feet away for that unexpected up-close encounter with a life-list bird. The lenses are fully multicoated with GPObright antireflection film and the Schmidt-Pechan roof prisms are treated with dielectric coating, both designed to enhance color and contrast while minimizing color fringing. The lightweight magnesium body is covered with rubber armoring for durability and a comfortable grip.
