The Passion ED series of Binoculars are a perfect choice for bird watching, wildlife observation, and other outdoor activities. They feature a magnesium alloy frame to keep weight to a minimum. Rotating eye cups enhance comfort, and rubber armor provides protection against impacts and a positive grip. Like all products offered by German Precision Optics, the Passion ED Binoculars offer excellent optical quality. This is thanks to GPObright lens technology – a vacuum applied coating that allows 99.7% of available light to pass through each optical surface, resulting in an extremely high light transmission. Image quality is further enhanced thanks to high-grade ED glass elements, as well as an optimal exit pupil for a brighter viewing experience.
