Engineered with a wide field of view and exit pupil and a short minimum focus distance to deliver detailed views for a variety of glassing tasks, the Kowa 8x42 BD II XD Binoculars feature phase-corrected and dielectric-coated Schmidt-Pechan roof prisms with anti-reflection fully multi-coated extra-low dispersion XD objective lenses that work together to produce a versatile and capable optic with bright and clear high-contrast images and accurate color rendition. The combination of 8x magnification and 42mm objectives produces a long eye relief and wide exit pupil to make observations comfortable with the ability to gather the light required to keep views bright and crisp in low or challenging conditions, such as at dawn and dusk, so you can move freely as you hike a trail, climb to an observation deck, or just sightsee around the city.
