Hawke Endurance ED 12x50

• 12× Magnification — Highest in the Endurance ED Binocular Lineup: The 12× magnification provides the highest image scale in the Endurance ED range, delivering the detail resolution needed for demanding observation tasks at extended distances — identifying trophy quality, counting antler points, or resolving fine plumage detail in birding — where the additional magnification over 10× produces a meaningful practical difference. A tripod or stable rest is recommended at 12× to eliminate hand-shake blur during extended observation.
• Extra-Low Dispersion Glass with Phase Corrected BAK-4 Roof Prisms: The Extra-Low Dispersion (ED) glass reduces chromatic aberration and colour fringing on high-contrast subjects — particularly relevant at 12× where the higher image scale amplifies any optical shortcomings. The phase corrected BAK-4 roof prisms and fully multi-coated lenses maintain resolution and contrast across the full aperture, delivering a clear, well-resolved image for detailed subject identification.
• 50mm Objective Lens for Adequate Low-Light Performance at 12×: The 50mm objective lens provides an exit pupil of 4.2mm at 12× — maintaining adequate image brightness for hunting and wildlife observation in typical field lighting conditions. The 50mm objective is the minimum practical aperture for a 12× binocular intended for field use, as a smaller objective at this magnification would produce a very small exit pupil and a noticeably dim image in variable light.
• Wide Apparent Field of View at 12×: The field of view of 91 metres at 1,000 metres and apparent field of view of 62° are notably broad for a 12×50 binocular — supporting landscape scanning and target tracking at the high magnification without the extremely narrow tunnel view typical of some binoculars in this class.
• Waterproof and Fogproof with Tripod Thread and Stay-On Covers: The body is nitrogen purged, waterproof, and fogproof with a high-grip rubber exterior. The built-in ¼"-20 UNC tripod mounting thread enables tripod use — strongly recommended at 12× for steady, fatigue-free extended observation. Twist-up eyecups with position stops and 15mm of eye relief accommodate both bare-eyed and eyeglass-wearing users. Stay-on objective lens covers remain attached during use.

About the Endurance ED Binocular Series

The Endurance ED series is Hawke's mid-tier binocular range, built on the H5 optical system and positioned between the entry-level Nature-Trek and Vantage series and the flagship Frontier ED X above it. The series is designed for hunters, birders, and nature observers who want Extra-Low Dispersion glass and phase-corrected prisms in a practical, field-ready package at an accessible price point.

All Endurance ED models feature ED glass, phase corrected BAK-4 roof prisms, fully multi-coated lenses, nitrogen purging, waterproof and fogproof sealing, twist-up eyecups with position stops, stay-on lens covers, and a built-in ¼"-20 UNC tripod mounting thread. The series spans 8×32, 10×32, 8×42, 10×42, 10×50, and 12×50 configurations. The 12×50 is the highest-magnification model in the lineup, intended for users who need maximum image scale for demanding observation at extended distances.

About the Model (Hawke Endurance ED 12x50 — Green)

The Hawke Endurance ED 12x50 is the highest-magnification model in the Endurance ED binocular range, designed for hunters, birders, and nature observers who need maximum image scale for detailed identification at extended distances. The 12× magnification with a 50mm objective lens delivers a field of view of 91 metres at 1,000 metres and an apparent field of view of 62° — broad for the 12×50 class — while the exit pupil of 4.2mm maintains adequate image brightness for typical field lighting conditions.

The ED glass lens elements reduce chromatic aberration and colour fringing at 12×, where colour accuracy and resolution are most critically affected by any optical shortcomings. The phase corrected BAK-4 roof prisms and fully multi-coated lenses deliver a clear, well-resolved image for the demanding identification tasks this magnification level is suited to. The close focus distance of 2.5 metres extends usability to moderate close-range subjects.

The body is nitrogen purged, waterproof, and fogproof with a high-grip rubber exterior. The built-in ¼"-20 UNC tripod mounting thread enables tripod use — strongly recommended at 12× for steady observation during extended glassing sessions. The twist-up eyecups with position stops and 15mm of eye relief accommodate both bare-eyed and eyeglass-wearing users. Stay-on objective lens covers remain attached during use. Weight is 805 g and dimensions are 120–135 mm wide × 167 mm high.
