Barska's 10x50 Focus Free Binocular gives you the power to instantly view even the most elusive creature when there's no time to be fumbling with a focus knob. BK7 porro prisms and blue-tinted fully coated optics increases light transmission and helps to reduce glare, while preserving your ability to accurately see colors. An ultra-wide 70° apparent angle of view provides an exceptional panoramic view that, when coupled with the focus-free optical system, produces a truly immersive observational experience in the field, on the trail, or at the stadium.
