Digital Camera World Verdict

An outstanding pair of roof prism binoculars, the Monarch HG 10x42s are slim, lightweight and incredibly easy to use. Nitrogen-filled, they’re also fog-proof and waterproof which means they’ll keep up with adventurous photography, in any weather conditions. We would recommend these 10x42s to anyone who wants some of the best optics on the market. The only way they could improve is if there was in-built stabilization – otherwise, they’re almost faultless.

The Nikon Monarch HG 10x42 binoculars are roof prism binoculars designed with a Field Flattener Lens System and Extra-low Dispersion (ED) glass to provide some of the sharpest edge-to-edge views you can get. Built to the same high standard as their premium lenses, the Monarch HG line is designed for wide-field observing of birds and tracking of wild animals. Everything that these binoculars ship with feels premium, whether it’s the carry pouch, the neckstrap, or the lens caps.

At 10x magnification, they’ll get you comfortably close, visually, to your subjects, and with 42mm objective lenses they’ll let in a good amount of light to perform well even during twilight hours. Fortunately, these binoculars have been purged with Nitrogen which means they won’t fog up when observers move between cold and warm areas, plus their build is completely waterproof so you can use them in pouring rain or, if you drop them in a body of water, you can comfortably take your time fishing them out as they’ll be fine in up to five meters for up to ten minutes.
