Nikon's Aculon A211 are porro binoculars that are suitable for users looking for a versatile pair of binoculars. The A211 has a rubber coating and ergonomic design, making it easy to hold securely. The lens elements with multi-layer coating offer a sharp and clear image, and the aspheric eyepiece lenses ensure that the image doesn't distort across the entire surface of the lens. The generously proportioned focus wheel allows you to easily focus on all the beauty nature has to offer. The 7.1mm exit pupil and the 17.6mm eye distance further contribute to optimal viewing comfort.
