Nikon Monarch HG 8x30 BinocularThe Nikon Monarch HG 8x30 Binoculars take the quality of the 42mm models and present them in a smaller, lighter size. The Monarch HG 8x30 binoculars weigh a mere 15. 9 ounces while providing wide 435' field of view at 1000 yds. In our tests, they performed better than their nominal 6. 6' close focus and had a relatively deep field of focus, aided by field flattener eyepiece lenses. Eye relief is 16. 2mm. A locking diopter ring prevents diopter drift.
