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 ocular lenses ensure that the image does not distort across the entire surface of the lens. The generously proportioned focus wheel lets you easily focus on all the beauty nature has to offer. The 4.2mm exit pupil and the 12mm eye distance further contribute to optimal viewing comfort.
