The 8x40 NatureView Backyard Birder Binocular Kit from Bushnell includes a birding field log and a fixed-magnification optic designed for mid-range glassing. A multicoated lead-free optical path enhances contrast while using responsibly-sourced environmentally-friendly glass elements and prisms. This model of the NatureView series is configured with a Porro prism design that renders more depth of field compared to roof prism binoculars. The binocular weighs less than 2 lbs and features a non-slip rubber-armored body, which improves handling and makes it well-suited for birding and other long-duration activities. A 56° apparent viewing angle displays a broad image of the field of view, equipping the 8x40 Backyard Birder with image quality adequate for most recreational observations.
