The Porro prism configuration 10x42 NatureView Binocular from Bushnell is a fixed-magnification optic designed for mid-range outdoor glassing tasks. This model of the NatureView series binocular uses a Porro prism design, which enables more depth of field compared to roof prism designs. The binocular weighs less than 2 lbs and features a rubber-armored weather-sealed housing that makes it well-suited for day hikes and other recreational activities.
A fully multi-coated lead-free optical path provides NatureView binoculars with enhanced contrast and image clarity using responsibly-sourced environmentally-friendly glass elements and prisms. The oculars have twist-up eyecups and 15mm eye relief, delivering a comfortable viewing distance even while wearing eyeglasses. A 66° apparent viewing angle provides an immersive image of the field of view, equipping the 10x42 NatureView for birding and almost any outdoor observation.
