Nikon ProStaff 12x25 ATB

The ProStaff 12x25 ATB are mid-range, compact Nikon binoculars primarily intended for birding, though suitable for other outdoor activities. With a 25mm objective lens diameter and weight under 13 ounces, the model is highly portable, featuring a rugged polycarbonate, rubber-armored body designed for waterproof, fog-proof performance.

Versions with 8x and 10x magnification are also available. The lenses feature multiple coatings of anti-reflective compounds, optimizing light transmission. The 12x25 ATB feature 15.9mm eye relief, enough for comfortable use with eyeglasses, and central diopter adjustment, for correcting differences between eyes. The lenses and prisms are made with Eco Glass, which was manufactured without the use of lead or arsenic, Nikon claims.
