Amcrest 10x42 Roof Prism Binoculars Black AM-B1042-B

10x42 HD Binoculars with Phone Adapter

Amcrest 10x42 Roof Prism Binoculars deliver 10x magnification through a 42mm objective lens. The BAK-4 prism system and fully multi-coated optics reduce reflections for brighter images. A universal phone adapter is included for digiscoping. The lightweight chassis weighs 1.19 lbs and measures 4.72 x 2.05 x 5.71 inches.

Suited for daytime and low-light viewing.

These binoculars perform well for bird watching, travel, stargazing, hunting, concerts and sports in daylight or low-light conditions. The 13.12-foot close focus allows near-subject observation. The 6° angle of view and 315-foot field of view at 105 yards are adequate for scanning. They cannot form an image in complete darkness, so buyers needing night-vision capability should look elsewhere.

56–72 mm interpupillary adjustment

The twist-up eyecups and 56mm to 72mm eye-width range let most users achieve a full field of view. Eye relief of 16.5 mm accommodates spectacle wearers, while the 4.2 mm exit pupil matches the 10x42 design. If your interpupillary distance falls outside the 56–72 mm range, you will not be able to merge the two images into one.
