Nikon MONARCH M5 12×50
Experience powerful long-distance observation with the clarity, brightness and natural colour reproduction of Nikon's premium optical technology. The MONARCH M5 12×50 combines high-magnification reach with large 50mm objective lenses, ED glass and advanced prism coatings in a remarkably lightweight, weather-ready body.
Greater Reach. Brighter Detail.
Designed for demanding birdwatching, nature observation, marine use and stargazing, the MONARCH M5 12×50 delivers the additional reach of 12× magnification without the bulk normally associated with large-objective binoculars. Its 50mm objective lenses gather abundant light, helping reveal fine detail and natural colour during early mornings, late afternoons and other challenging viewing conditions.
Premium Nikon Optical Performance
Extra-Low Dispersion Glass
Nikon ED glass helps correct chromatic aberration and reduce colour fringing, producing sharper, higher-contrast views with more natural colour reproduction.
Large 50mm Objective Lenses
The large objective lenses offer strong light-gathering performance and resolution, delivering bright, detailed views for wildlife, distant landscapes and the night sky.
Dielectric Multilayer Prism Coating
A dielectric high-reflective multilayer coating increases light transmission through the roof prisms for a brighter image and faithful colour reproduction.
Phase-Correction Coating
Phase-correction coatings are applied to the roof prisms to improve resolution, definition and contrast throughout the observed image.
Fully Multilayer-Coated Optics
All lenses and prisms are multilayer coated to improve light transmission and provide clear, bright viewing across a wide range of outdoor conditions.
Immersive Wide Apparent Field
A 60.8° apparent field of view creates a spacious and immersive viewing experience while retaining the long-distance detail of 12× magnification.
Made for Real-World Observation
Waterproof and Fogproof
O-ring seals and nitrogen gas provide waterproof performance to a depth of 1 metre for up to 10 minutes, while helping prevent internal fogging during sudden temperature changes.
Lightweight 650g Construction
A strong fibreglass-reinforced polycarbonate resin body helps reduce overall weight while retaining the durability required for regular outdoor use.
Comfortable Rubber Armour
Protective rubber armouring offers a secure, comfortable grip and additional resistance against everyday bumps and knocks.
Turn-and-Slide Eyecups
Multi-click rubber eyecups make it easy to set the correct eye position, while 16.4mm eye relief supports comfortable viewing for many eyeglass wearers.
Flip-Down Objective Caps
Attached flip-down objective lens caps help protect the lenses and reduce the risk of losing the caps while observing in the field.
Tripod Adaptable
The binocular can be mounted to a tripod using the optional Nikon TRA-3 tripod adaptor, providing additional stability for extended high-magnification viewing.
Ideal For
Long-Distance Performance Without Unnecessary Bulk
At only 650g, the MONARCH M5 12×50 combines the light-gathering performance of a 50mm binocular with a body that remains comfortable to carry and manoeuvre in the field.
Technical Specifications
Waterproof testing does not mean the binocular is designed for underwater operation. Apparent field of view is calculated in accordance with the applicable ISO 14132-1 standard. Specifications are subject to manufacturer change.
