Featuring BAK4 Porro prisms and aspherical optical elements, these binoculars offer edge-to-edge sharpness and a wide angle of view, making them ideal for birdwatching, wildlife observation, and landscape spotting. Fully multicoated optics ensure high light transmission for bright, clear images even in low-light conditions.
Versatile Magnification and Focus
With an 8-16x zoom range and 21mm objective lenses, you can effortlessly switch from wide-angle viewing to detailed close-ups. The binoculars provide a 5° field of view at 8x and 3° at 16x, allowing you to track distant targets smoothly. The minimum focus distance of 63.8’ / 19.4 m lets you study nearby objects such as footprints, markings, or landscape features in fine detail.
Comfortable and Practical Design
Designed for extended use, these binoculars feature a single-piece objective frame for synchronised interpupillary adjustment, sliding rubber eyecups for eyeglass wearers, and a contoured body for a secure grip.
