The Nikon 10x42 Prostaff 5 Binocular (BAA821SA) combines a weather-sealed housing and fully multi-coated optics to create a general-purpose set of glasses for mid-range viewing tasks. This configuration of the Prostaff 5 features a 52° apparent viewing angle and 4.88 m minimum focus distance, making the 10x42 ideal for nature enthusiasts and sports fans. Nikon's Eco-Glass optics are made of responsibly-sourced material that does not contain lead or arsenic.
Fiberglass-infused polycarbonate allows the Prostaff 5 housing to be lightweight while remaining shock-resistant and durable. Additionally, the housing is nitrogen-filled for fogproof performance, and it is rubber armored for slip-resistant handling. A 15mm eye relief and Turn-and-Slide eyecups with several click-stop positions enable comfortable viewing distances even when wearing eyeglasses.
