Key Features
  • Ideal for Glassing Across Vast Distances

Nikon Monarch M5 12x42 Overview

From Manufacturer

Improving on their Monarch 5 design, Nikon's black 12x42 Monarch M5 Binoculars is ideal for use in wide-open terrain, like what's in the American West, when you need to scan for subjects and make positive identification. They benefit from a wider field of view than their predecessor to present you with a more immersive observational experience, with the same focus on comfort and performance the Monarch line is known for. Featuring extra-low dispersion glass elements with anti-reflection fully multicoated optics and highly reflective dielectric-coated and phase-corrected roof prisms, the Monarch M5 produces bright and clear high-contrast images with true-to-life color and minimal color fringing.

Optical Performance
  • The powerful magnification allows for detailed observation of distant subjects across vast flat ground like the prairies of the American West
  • Larger objective lenses improve light-gathering ability without adding excessive bulk or weight
  • Roof prism light path ensures optical tubes remain thin for a compact form factor
  • Extra low-dispersion glass reduces chromatic and spherical aberrations for increased contrast, improved color rendition, and sharpness without distortion across the entire field of view
  • Phase-correcting prism coatings reduce internal interference to improve light transmission, contrast, and resolution
  • Anti-reflection fully multicoated optics maximize light transmission across the entire visible spectrum for accurate color rendition and improved contrast and clarity
  • Highly reflective multilayer dielectric prism coatings boost internal reflection to >99% to maintain image brightness and improve contrast and clarity
  • Improved wider field of view than previous models presents a more immersive observational experience
Use and Handling
  • High-eyepoint design provides ample space between your brow and the eyecups for a clear field of view, even when you're wearing glasses
  • Closed-bridge configuration provides a solid and stable platform for the internal focusing mechanism
  • Large slip center focus wheel allows for precise focus control, even while wearing gloves
  • Right eye dioptric adjustment collar helps to compensate for individual eye prescription
  • 56-72mm interpupillary distance range allows easy use by a wide variety of people
  • Twist-up/click-stop rubber eyecups for use with or without eyewear
  • Tripod mountable with optional adapter for hands-free use
  • Comfortable exit pupil will cover most pupils as they open when the light is fading to keep the full scene in view
Construction Details
  • Environmentally friendly Eco-Glass is made without lead or arsenic
  • Textured protective rubber armoring provides a slip-resistant grip, especially in cold and wet weather
  • Nitrogen filled and O-ring sealed to be waterproof and resistant to internal fogging when moving through extreme temperature changes and environmental conditions
  • Black coloring allows it to remain inconspicuous in all environments
  • One-piece tethered ocular rainguard protects eyecups from water pooling in them from rain or spraying water when hanging from the neck
  • Tethered fold-down objective lens caps prevents losing them during observation sessions

Nikon Monarch M5 12x42 Reviews

bird watching at the Wildlife Preserve

By Anita
Rated 5 out of 5

Being able to adjust the binoculars at the eye piece as well as along the lens enables us to see near and far along the lake shoreline and into the center of the pond. This product is so much better than our last pair even though they were designed for birdwatching

Top-notch Binocs!

For PA deer hunting and looking through some cover and brush for horns which is best 8x42 or 10x42 or 12x42 ? o other
Asked by: STEPHEN
The Nikon 12x42 Monarch M5 Binoculars would be the best for deer hunting and looking through some cover and brush. The issue is being able to hand hold the 12X binoculars without shaking. When one tries the 12X one out, very often people choose the 10X pair, because it is easier to hold the 10X power binoculars. The solution is to use a tripod with the Nikon 12x42 Monarch M5 Binoculars. https://bhpho.to/3Zo9k33
