8x - 20X Compact Zoom Binocular 25mm Objective Prism Glass BK-7 Sportstar Zoom binocular
The 8-20x25 Binocular is a lightweight and compact optic with a powerful magnification to bring distant subjects up close for detailed observations. The wide 8-20x variable magnification range allows the user to observe a large area and then zoom into a particular point for a closer look. A zoom thumb lever conveniently located by the right eyepiece allows for quick and smooth zoom adjustments
It features a fully multi-coated optical path and an ergonomic housing — making it an ideal companion for outdoor enthusiasts, sports spectators, and city sightseers alike
Complementing the travel-friendly size are aspherical lenses that reduce the curvature that can distort the field of view as well as BK7 reverse Porro prisms that work together to present flat high-contrast images with lifelike color and consistent center-to-edge sharpness.
Combined with a 7 m close focus distance, this 8-20x25 binocular is ready for almost any mid- to long-range glassing task.
