Product Description

The 10×42 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 colour 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.
