Bushnell Natureview 8x40 Backyard Birder Tan Porro

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.Optical Performance:- 8x magnification, 40mm objectives- Porro prism design- Multi-coated optics- Lead-free glass elements and BK-7 prisms- 56 apparent viewing angle- 365 ft (111m) at 1000 yd field of view- 14 ft (4.3m) minimum focus distanceUse and Handling:- Center focus wheel with ergonomic texture and ridges- Fold-down rubber eyecups- Tripod mounting socketConstruction Details - Rubber armored body for non-slip gripSpecifications:- Prism Type: Porro - Magnification: 8x - Objective Lens Diameter: 40mm - Angle of View: 7 (actual) - Field-of-View: 365' 1000 yd- Minimum Focus Distance: 14'- Exit Pupil Diameter: 5mm - Eye Relief: 14mm- Focus Type: Center - Tripod Mount: Yes- Weight: 25.4 oz
