Zeiss 8X42 Terra ED Binocular (Gray)
The gray ZEISS Optics 8x42 Terra ED Binoculars feature a redesigned ergonomic chassis that makes holding them more comfortable, especially during long glassing sessions. Optically, they retain the exceptional elements that are the hallmarks of the Terra ED, including compact Schmidt-Pechan roof prisms, SCHOTT extra-low dispersion (ED) glass, and proprietary multicoatings.
These complementary technologies and elements work together to produce an immersive observational experience that presents clear and bright views with accurate color representation and virtually zero distortion across the entire field of view. Adding to the binoculars' usability is a short 5.25-foot close-focus distance that gives them the ability to resolve feathers or leaves in fine detail.
PRODUCT FEATURES
Optical Performance
*8x magnification
*42mm objective lenses
*Roof prism optical path
*The compact Schmidt-Pechan prism design corrects the view while allowing for thinner optical tubes versus the more common Abbe-Koenig design.
*SCHOTT ED glass elements reduce chromatic and spherical aberrations to produce views with true color rendition, and without halos, diffraction, or distortion across the entire field of view.
*ZEISS proprietary hydrophobic multicoated optics shed dust, dirt, and oils while improving light transmission, color rendition, sharpness, and contrast.
*Short 5.25-foot close-focus distance.
*376.5' field of view at 1000 yards.
Use and Handling
*Closed-bridge configuration.
*Large fast-focus center wheel.
*±3 right-eye dioptric correction.
*58 to 75.5mm interpupillary adjustment range.
