The 8x40 NatureView Backyard Birder Binocular from Bushnell is a fixed-magnification optic designed for mid-range 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 body that makes it well-suited for birding and other recreational activities. A multi-coated lead-free optical path provides NatureView binoculars with enhanced contrast using responsibly-sourced environmentally-friendly glass elements and prisms. A 56 apparent viewing angle provides a broad image of the field of view, equipping the 8x40 Backyard Birder with a suitable view for most observations.
