Konus Emperor Features The Konus Emperor binoculars are built around special BAK-4 roof prisms finished with Phase Correction coating a technique that forces light beams back into phase as they pass through the prism system. This improves image definition and contrast noticeably compared to standard prism coatings particularly when picking out fine detail on distant game or targets. Fully multi-coated lenses further improve light transmission helping maintain a bright clear image even in low light conditions near dawn or dusk. At 10x magnification with a 42mm objective and a 4.1mm exit pupil these binoculars balance strong magnification with enough light gathering capability for extended glassing sessions making them equally at home on a treestand or a mountain glassing knob. A waterproof nitrogen purged body keeps moisture and internal fogging out of the optical system making these binoculars dependable across changing weather conditions in the field. Wide angle eyepieces combine with a 315 foot field of view at 1000 yards to make target acquisition faster when scanning open terrain for moving game. Extra long eye relief and twist-up eyecups accommodate users wearing glasses while the center focus system allows quick precise adjustment between near and far subjects without fumbling for a separate diopter dial. Constructed with a metal body and weighing 26.8 ounces the Konus Emperor is built to hold up through repeated field use for hunters birdwatchers and outdoor enthusiasts who need a rugged optic they can trust season after season.
