Why pick Nikon Monarch M5 8x42?
Extra-low dispersion (ED) glass reduces color fringing around high-contrast edges like a bird against a bright sky, and makes colors look cleaner.
At 8x42 you get a steady, bright image with a wide view for finding birds quickly. Nikon’s Monarch line is a long-standing favorite for birders moving past entry-level optics.

The Nature DX gets the fundamentals right: BaK-4 prisms, phase-coated optics, a wide 7.4° view and a close focus of about 6.5 feet for butterflies and nearby birds.
Image quality falls behind ED-glass pairs at the edges and in low light, but it is a real birding binocular, not a toy.

- Want a gift that will get used

8x42 for most birding
8x gives a steadier, wider view than 10x. The 42 mm objective gathers enough light for shade and dusk.
ED or HD glass
Reduces color fringing and improves sharpness, the most visible upgrade above entry level.
Eye relief
Glasses wearers need about 15 mm or more of eye relief to see the full view.
Weatherproofing
Waterproof, nitrogen- or argon-filled bodies won’t fog inside.

Frequently asked questions about binoculars
8x42 or 10x42 for birding?
8x42 for most people: wider, steadier and brighter. 10x helps for distant waterfowl and raptors if you have steady hands.
What does 8x42 mean?
8 times magnification and 42 mm objective lenses.
Do I need ED glass?
Not to enjoy birding, but it’s the most visible upgrade in sharpness and color.
Roof or porro prism?
Roof prisms are slimmer and easier to waterproof; good porros can offer great value.
How do I clean binocular lenses?
Blow off grit first, then use a lens brush and lens cloth. Never wipe sand across the glass.
What is eye relief, and do I need more with glasses?
Eye relief is how far from the eyepiece your eye can be and still see the full view. Glasses hold your eyes farther back, so eyeglass wearers usually want about 15 mm or more and should twist the eyecups down.
How did we pick these binoculars?
We compared configuration, glass and coatings, field of view, close focus, weatherproofing and warranty from manufacturer specifications, and birding guidance from the Cornell Lab of Ornithology and Audubon.
We have not hands-on tested these products; we compare published specifications, independent measurements and manufacturer documentation, and we update this page when models change. Read the full methodology.
