Zeiss Terra ED 8x42 Binoculars - Black
44-4205Regular price $399.99
At the core of Terra ED series optics are fully multicoated SCHOTT ED glass lenses designed to maximize light transmission and render contrast-rich images. Thanks to a space-saving Schmidt-Pechan roof prism design and lightweight composite housing, this binocular weighs less than 2 lbs. Complementing the high-transmission optical path and modest form factor, the Terra ED has a nitrogen-filled housing that provides fogproof performance and submersion tightness to a depth of approximately 3 ft, preparing these binoculars for almost any outdoor observation.
This configuration of the Terra ED binocular features 8x magnification and an immersive 56Â° apparent viewing angle. These features, in addition to the 18mm eye relief, equip the 8x42 optic for comfortable glassing. These glasses also boast the ability to focus down to less than 6 ft, allowing observers to get up close to the bird or other nearby subject of interest. A textured center focus wheel and twist-up rubber eyecups supply additional handling features that enhance the overall ergonomics of the Terra ED and help make it a full-featured binocular for close to mid-range glassing tasks.
