An 8x42 with a 335-foot field and 19.5 millimeters of eye relief is the birding specification we keep coming back to, and the Monarch M5 is the cleanest expression of it in this group. The 8x view is easier to hold steady than a 10x when a warbler is moving through leaves, while the 42-millimeter objective still gathers enough light for dawn and dusk. We also like that the eye relief leaves room for glasses; you can keep your specs on and still see the full field.
The glass is the reason this one sits at the top. Nikon uses ED glass and dielectric prism coatings, the kind of specification that matters when you are trying to separate a thrush from the leaf litter rather than just count branches. The body is nitrogen-purged and O-ring sealed, so rain and fog are not a reason to put it away. At 1.4 pounds it is light enough for a long walk, and the closed bridge gives your hands a natural place to steady it.
This is the binocular we recommend as the default for most birders. It does not have the reach of a 10x when a hawk is thermaling over a distant ridge; for that, the Vortex Crossfire HD is the more useful tool. But the Monarch's wider field and longer eye relief make it the easier binocular to live with hour after hour, and that is the trade most birders should take.
The detail we appreciated most in use is the large center focus knob: it falls under a finger without forcing you to break your grip, and the twist-up eyecups have enough friction to stay where you set them. Those are small things until you are adjusting focus with one hand while the other hand is busy.

- Wide 335-foot field finds birds quickly
- Long 19.5mm eye relief suits glasses
- ED glass and dielectric prism coatings

For birders who want one binocular to cover woodland, water, and everything between, the Monarch M5 is the most complete package here.
