Leica's olive green 10x42 Noctivid Binoculars represent the perfect combination of form and function in a single optic. They are designed with an array of complementary technologies to produce bright and clear color-neutral images, while fitting comfortably in the hand for long, fatigue-free glassing sessions.

The Noctivid's performance starts with the use of SCHOTT High Transmission glass with a 12-element lens configuration and their HighLux-System anti-reflection multi-coatings, followed by phase-corrected compact roof prisms. These features produce bright and clear high-contrast images with accurate color rendition across the entire visible spectrum. Internal baffles limit scattered light in the optical tubes, which can affect clarity and contrast, while an innovative lens design and internal field flatteners ensure edge-to-edge clarity across the entire wide-angle field of view. The wide viewing angle and relatively high 10x magnification allow you to take in sweeping views while also giving you the ability to make detailed observations of distant objects. The wide viewing angle also helps to mitigate the common occurrence of disorientation that often accompanies high magnifications when using the optic on rolling seas or airborne platforms.

The Noctivid binoculars are made with a dual-hinge / open-bridge that provides added gripping surface area while reducing the overall weight without sacrificing strength or stability. Their chassis is made of a lightweight and strong magnesium alloy that, when combined with the bridge configuration, further reduces the weight while shifting the center of gravity to the natural hand position, which translates to an improved handling experience with greatly reduced fatigue, allowing you to hold the binoculars for extended periods of time. To withstand the rigors of extensive outdoor use, all of the metal surfaces are treated with a proprietary varnish coating to resist corrosion and wear and the optical tubes are nitrogen filled and O-ring sealed to be fogproof, waterproof, and submersible.

Optical Performance

  • High 10x magnification enables detailed observations of distant subjects
  • 42mm objective lenses improve light-gathering ability for enhanced low-light performance such as at dawn and dusk or when peering into dense brush
  • Compact roof prism optical path helps to maintain a compact form factor for easier handling
  • SCHOTT HT (High Transmission) glass and 12 lens elements ensure accurate color rendition with limited distortion
  • Multi-layer high-temperature plasma anti-reflection lens coating deposition process ensures balanced light transmission across the entire visible spectrum
  • P40 phase-correcting prism coatings increase light transmission while improving contrast and clarity
  • HighLux-System (HLS) maximizes light throughput to improve color rendition and contrast
  • Internal baffle system reduces scattered light, which can interfere with contrast, color, and clarity
  • Hydrophobic AquaDura coatings on external optical surfaces allow dirt, dust, and fingerprints to be removed easily
  • Lens design and integrated field flatteners reduce spherical aberration and distortion across the entire field of view for edge-to-edge sharpness
  • Wide 64° apparent angle of view minimizes the appearance of the distracting hand shake that is common when holding high-power optics, while presenting a spacious and immersive observational experience
  • 337' field of view at 1000 yards

Use and Handling

  • Open-bridge/Dual-hinge configuration provides additional gripping surface area for better handling
  • Large slip-resistant center focusing wheel is easy to manipulate in cold and wet weather, or while wearing gloves
  • 56-74mm adjustable interpupillary distance allows easy use for a wide variety of people
  • ±4 right-eye dioptric correction range enables users to compensate for individual optical prescriptions for tack-sharp images
  • Twist-out 4-position click-stop eyecups for comfortable use with or without eyewear
  • Long 19mm eye relief ensures comfortable use with reduced eye strain, especially during long glassing sessions
  • 4.2mm exit pupil will cover most pupils when they open and dilate in low-light to ensure the entire scene stays in view without vignetting

Construction Details

  • Bridge design helps to reduce overall weight without sacrificing strength of stability
  • Lightweight and durable magnesium alloy chassis
  • Protective olive green rubberized armoring provides a slip-resistant grip in all weather conditions
  • Nitrogen filled for fogproof performance, especially when moving through extreme temperature changes and environmental conditions
  • O-ring sealed to be submersible to 16.5' (5m)
  • Proprietary varnish coating protects metal surfaces from corrosion and wear

Lecia Noctivid = Exceptional !

By George

Superb. The depth of field and color rendition on these bins is the best out there. Swaro NP Pure gets most of the accolades but these are better. Fit and finish are better. Hand feel is better. Eye cups and eye relief are better. The Swaros are excellent but the Noctivids give the viewer more of a realistic view without the flat focal plane that Swarovski has.

Great bins. One glaring issue

By Richard

The optics of these binoculars are outstanding. Everything you would expect from Leica. Ergonomics great too. However, there is one problem that binoculars of this class and high cost shouldn't have. When you extend the eyecups the routing in the metal that allows the eyecups to twist catches sunlight from the side. This ruins an otherwise perfect view as the light glaresviff the edge. Imagine a bright light always present in your peripheral vision. These are top of the range Leica. I doubt this problem exists in bargain bin binoculars. It certainly doesnt exist in my other Leicas. Given the cost I think this is unforgivable, hence the 3 stars.

I always wanted this binocular. I haven't used it much, but I did take it outside for a test run, and I must say I was impressed. The way the separate focus for the right eye works, is better than any system I've seen, and the main center focus is what makes the name Leica, the one that's worth the extra money. Its like silk and the image is unbelievably sharp, crisp and bright. Sure, it's expensive, but if you want the best, this is the one.
