FUJINON KF Binocular 10x42 H-R II Made in Philippines
The 10x42 KF Binoculars from Fujinon utilize phase-corrected BAK4 roof prisms with anti-reflection fully multi-coated optics to create images that are clear and bright with minimal distortion and true color transmission. The 10x magnification is ideal for resolving detail in heavy brush or at long distances where accurate identification is critical. With a long 13mm eye relief, a comfortable 4.2mm exit pupil, and a 60° wide apparent angle of view, the normal limitations of high-powered binoculars, such as visible hand shake, are reduced for a more immersive observational experience.Built for the rigors of constant outdoor use, the housing features an armored exterior that protects the binoculars from drops and impacts as well as helps to provide a slip-resistant grip, especially when it is cold and wet out. The optical tubes are nitrogen filled and O-ring sealed for waterproof and fogproof performance in all weather conditions.Optical Performance10x magnification42mm diameter objectiveBAK4 roof prismsPhase-corrected silver-coated prisms provide enhanced color rendition and contrastAnti-reflection fully multi-coated optics reduce light loss and increase overall image brightness, color, and clarity315' field of view at 1000 yardsWide 60° apparent angle of viewUse and HandlingCenter focus wheelRight-eye dioptric adjustment56-74mm interpupillary adjustment rangeComfortable 4.2mm exit pupilLong 13mm long eye reliefConstruction DetailsLightweight and durable aluminum-alloy chassisProtective rubber armoring provides slip-resistant gripWaterproof and nitrogen filled for fogproof performanceWeight: 23.5 ounces
