Hawke Endurance ED 8x42

• 42mm Objective Lens for Enhanced Low-Light Performance: The 42mm objective lens delivers an exit pupil of 5.3mm — substantially larger than the 4mm of the 8×32 model — supporting a brighter, more accessible image in the reduced-light conditions of early morning and late evening hunting, wildlife observation, and birdwatching. The larger objective is the primary practical distinction between the 8×32 and 8×42 configurations within the Endurance ED lineup.
• 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. The phase corrected BAK-4 roof prisms and fully multi-coated lenses deliver a clear, well-resolved image across the field, maintaining resolution and contrast in all ambient light conditions encountered during typical field use.
• Wide Field of View at 8× Magnification: The field of view of 133 metres at 1,000 metres and apparent field of view of 61° provide a broad, comfortable sight picture for landscape scanning, wildlife observation, and fast target acquisition. The generous field supports extended glassing sessions during hunting and birdwatching without fatigue from a narrow or tunnel-like view.
• Practical All-Round 8×42 Configuration: The 8× magnification with 42mm objective is one of the most widely used binocular configurations in hunting and nature observation — providing a practical balance of image scale, light gathering, field of view, and manageable overall size. At 705 g, the Endurance ED 8×42 is well proportioned for extended all-day carry in the field.
• Waterproof and Fogproof with Tripod Thread and Stay-On Covers: The body is nitrogen purged, waterproof, and fogproof, with a high-grip rubber-coated exterior. The twist-up eyecups with position stops and 17mm of eye relief accommodate both bare-eyed and eyeglass-wearing users. A built-in ¼"-20 UNC tripod mounting thread enables tripod use. 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, covering the full range of hunting, birding, and nature observation requirements. The key distinction from the Frontier ED X is the use of silver mirror prism coatings rather than the dielectric mirror coatings of the H7 system.

About the Model (Hawke Endurance ED 8x42 — Green)

The Hawke Endurance ED 8x42 is Hawke's most versatile all-round binocular in the Endurance ED range, designed for hunters, birders, and nature observers who want the practical combination of 8× magnification, a 42mm objective lens, and ED glass performance in a field-ready H5 package. The field of view of 133 metres at 1,000 metres and apparent field of view of 61° provide a broad, comfortable sight picture across all intended applications, while the exit pupil of 5.3mm supports adequate image brightness in low-light conditions during the hunting periods most relevant to the model's primary users.

The ED glass lens elements reduce chromatic aberration and colour fringing, while the phase corrected BAK-4 roof prisms and fully multi-coated lenses maintain resolution and contrast throughout the field. The close focus distance of 2 metres extends usability to close-range subjects during birding and nature observation. The 17mm of eye relief accommodates both bare-eyed and eyeglass-wearing users comfortably.

The body is nitrogen purged, waterproof, and fogproof with a high-grip rubber exterior rated for demanding field use. The twist-up eyecups with position stops provide defined click positions for consistent eye relief across sessions. A built-in ¼"-20 UNC tripod mounting thread supports use on a tripod or binocular mount. Stay-on objective lens covers remain attached during use. Weight is 705 g and dimensions are 109–127 mm wide × 148 mm high.
