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.brbrA 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 16mm 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 8x42 NatureView for birding and almost any outdoor observation.brbrOptical Performancebrbr- 8x magnification, 42mm objectivesbr- Porro prism designbr- Fully multi-coated opticsbr- Lead-free glass elements and BaK-4 prismsbr- 66 apparent viewing anglebr- 435 ft 133m at 1000 yd field of viewbr- 12 ft 3.7m minimum focus distancebrbrUse and Handlingbrbr- Center focus wheel with ergonomic texture and ridgesbr- Twist-up eyecups for comfortable eye reliefbr- Tripod mounting socketbrbrConstruction Detailsbrbr- Nitrogen-filled housing provides fogproofwaterproof performancebr- Rubber armored body for non-slip grip in wet conditionsbrbrSpecificationsbrbr- Prism Type Porro br- Magnification 8x br- Objective Lens Diameter 42mm br- Angle of View 8.3 actual br- Field-of-View 435 1000 ydbr- Minimum Focus Distance 12br- Exit Pupil Diameter 5.2mm br- Eye Relief 16mm br- Focus Type Center br- Tripod Mount Yes br- Weight 27 oz
