About This Model
The Nikon ACTION ZOOM 10–22×50 is a full-size binocular designed for observing distant subjects at different levels of magnification. Its adjustable 10–22× zoom range allows users to change viewing power without switching instruments, while the 50 mm objective lenses and Porro prism optical system define its optical configuration.
At the minimum 10× setting, the binocular provides a real field of view of 3.9° and an exit pupil of 5 mm. Eye relief is 16.3 mm at this setting, and the central focusing system allows the image to be adjusted for different viewing distances. The zoom lever provides convenient magnification adjustment, although higher power can make hand movement more noticeable and the field of view narrower.
The body combines an aluminum-alloy construction with rubber armoring for grip and durability. Weighing approximately 950 g, this is a substantial binocular rather than a lightweight travel option. It can be mounted on a tripod using a separately available TRA-2 or TRA-3 adapter, which may be useful for extended observation at higher magnifications.
