12x42 ED Binoculars BAK4 Prism IP67 Waterproof

Clear, Stable Viewing for Serious Outdoor Use

The 12x42 ED binoculars are built for users who need reliable, high-quality vision in the field. With 12x magnification and a 42 mm objective lens, they bring distant subjects closer while maintaining clarity and detail for bird watching, wildlife observation, hiking, camping, travel, and hunting.

The Extra-Low Dispersion (ED) optical system helps reduce chromatic aberration, limiting color fringing around high-contrast edges and improving edge-to-edge sharpness. A BAK4 roof prism system and fully multi-coated optics (A5 Zeiss Red + FMC full band green film) support strong light transmission, giving bright, high-contrast images, especially at dawn, dusk, or in shaded environments. The 23 mm eyepiece and 4.2 mm exit pupil are designed to balance brightness and comfort for extended viewing sessions.

The binoculars use a metal frame with an outer rubber armor for impact resistance and a secure, non-slip grip. The IP67 waterproof and dustproof rating means the internal optical components are protected from rain, splashes, and brief submersion, as well as fine dust and dirt. A center-axis focusing system allows quick, precise focusing with one hand, while the 17 mm eye relief supports comfortable use, including for many eyeglass wearers. With a field of view of 123 m at 1000 m and a close focus distance of about 3 m, these binoculars are suitable for both distant landscapes and closer subjects such as garden birds or stadium events.

The compact body (approximately 18 x 6 x 13 cm) and about 700 g weight make them easy to carry in a pack or around the neck without excessive fatigue. Available in dark green, black, or blue, they are suited to both outdoor recreation and more tactical or field-oriented use.

Why It's a Smart Choice

• ED glass and BAK4 prisms work together to deliver sharp, high-contrast images with reduced color fringing.
• IP67 waterproof and dustproof construction protects the optics in rain, wet terrain, and dusty environments.
• Durable metal frame with rubber armor offers impact resistance and a stable grip for use in rugged conditions.

FAQ

Q: Can these binoculars be used in heavy rain?
A: Yes. The IP67 waterproof and dustproof rating means they are sealed against rain and brief immersion, making them suitable for use in wet and humid conditions.

Q: Are they suitable for eyeglass wearers?
A: The 17 mm exit pupil distance (eye relief) supports comfortable viewing for many eyeglass users. Adjust the eyecups and position the binoculars so the full field of view is visible.

Q: How far can I see with the 12x42 configuration?
A: 12x magnification brings distant subjects significantly closer while maintaining a stable image when handheld. You can observe subjects at long distances, but the actual detail you see depends on lighting, atmospheric conditions, and the size of the subject.

Q: Is this model good for low-light use?
A: The 42 mm objective lenses, 4.2 mm exit pupil, and fully multi-coated ED optics help maximize available light, making these binoculars suitable for early morning, late evening, and shaded environments.

Q: What focusing system does it use?
A: It uses a center-axis focusing wheel that adjusts both barrels simultaneously, allowing quick and precise focusing on subjects at different distances.
