The black 8x30 BX-1 Yosemite Binocular from Leupold is a compact optic featuring a Porro prism design and a fully multicoated optical path. Leupold outfitted this binocular with BaK4 prism glass, and its Porro prism configuration displays more depth of field than roof prism designs. The resulting images transmitted by the Yosemite binocular have lifelike depth and are crisp across the field of view.
A nitrogen-filled housing equips the Yosemite binocular for fogproof performance while its rubber armoring and textured ridges deliver a slip-resistant grip. Additionally, the binocular has a broad interpupillary adjustment range—its 50mm minimum interpupillary distance allows the Yosemite binocular to comfortably fit most children. Twist-up eyecups and an 15mm eye relief help to provide a comfortable viewing distance for children and adults alike.
