"The Nikon PROSTAFF 5 binocular comes in black finish and is available in 8x42, 10x42, 10x50 and 12x50 variations. It is built with Nikon's multilayer-coated lenses, which provide higher light transmittance across the entire visible light spectrum. By eliminating the loss of light due to reflection, these multilayered coatings ensure a more natural, clearer view. The PROSTAFF 5 utilizes Nikon's high-eyepoint design that provides a clear field-of-view and long eye-relief. The long eye-relief ensures a sufficient space between the user's eye and the binocular's eyepiece lenses to make them comfortable for everyone, even for those wearing eyeglasses. The multi-click turn-and-slide rubber eyecups make it easy to find the correct eye positioning to see the full field of view. Made with lead and arsenic free Eco-glass, the optics in the PROSTAFF 5 are not only of Nikon-grade quality, but are also environmentally friendly. The body is made with a fiberglass-reinforced polycarbonate resin, making it both lightweight and durable. It is also nitrogen filled and O-ring sealed for waterproof/fogproof performanc|Multilayer-coated lenses for bright images|Long eye relief design ensures a clear field of view, even for eyeglass wearers|Turn-and-slide rubber eyecups with multi-click facilitate easy positioning of eyes at the correct eyepoint|Waterproof (up to 1m/3.3 ft. for 10 minutes) and fog-free with nitrogen gas|Lightweight body uses fibreglass-reinforced polycarbonate resin|Eco-glass optics that are free of lead and arsenic are used for all lenses and prisms"
