ED Glass and Advanced Optical System
The X7's ED low-dispersion glass elements precisely correct chromatic aberration — the colour fringing and ghosting that affects standard binoculars at high magnification and distance. The result is sharper, more defined images with accurate, natural colour reproduction even in challenging lighting conditions. Combined with BAK4 prisms that optimise the internal light path and FMC multi-coating that maximises light transmission on every lens surface, the X7 delivers a viewing experience that rivals binoculars at significantly higher price points.
 
12x50 Magnification — Bright from Dawn to Dusk
The combination of 12x magnification and a 50mm objective lens gathers significantly more light than smaller aperture binoculars, producing noticeably brighter and clearer images in low-light conditions including early morning birdwatching, dusk wildlife observation, and overcast days. The 4.2mm exit pupil ensures the image remains bright and detailed at the eyepiece across the full field of view.
 
Wide Field of View and Fast Focus
A field of view of 262.5 feet at 1000 yards makes it easier to locate, track, and stay locked onto moving subjects — from fast-moving birds to sporting action and wildlife in open terrain. The central metal focus wheel delivers smooth, precise adjustment for quick target acquisition at any distance within the 4-metre close focus minimum.
 
IPX7 Waterproof and Built for the Outdoors
Nitrogen-filled sealed construction and IPX7 waterproofing protect the X7 against rain, humidity, and rapid temperature changes — maintaining clear, fog-free views in the most demanding outdoor environments. The durable eco-friendly rubber body absorbs impacts and provides a secure, non-slip grip in wet conditions.
