The black 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 525' close-focus distance that gives them the ability to resolve feathers or leaves in fine detailThe comfortable ergonomic chassis is made of a fiberglass-reinforced polycarbonate to help reduce weight without sacrificing strength - while adding impact and temperature resistance Being resistant to temperature changes ensures the housing will remain a constant temperature in cold and wet conditions It also prevents the expansion and contraction common in metal chassis that can cause the optical elements to move out of alignment over time and hinder the binoculars' ability to achieve sharp focus The chassis is covered in black rubber armoring for a slip-resistant grip It also helps protect against drops and impacts
