Nikon ACULON A211 8×42 Binoculars

ACULON A211 offers superior optical performance at an attractive price. Multilayer-coated lenses and a choice of large objective lens diameters provide extremely bright images and a wide field of view. Breathtaking visual experiences also result from the use of aspherical eyepiece lenses.

• Large objective lens diameter for a brighter and wider field of view
• Multilayer-coated lenses for bright, sharp images
• Aspherical eyepiece lenses for undistorted images across entire surface of the lens
• Turn-and-slide rubber eyecups facilitate positioning of the eyes
• Rubber armoring offers shock resistance and a firm, comfortable grip
• Tripod adaptable

Optical Performance

• Moderate 8x power magnifies images while preserving a wide field of view and exit pupil for easier, more comfortable viewing
• 42mm objective lenses improve light-gathering ability, even in challenging conditions such as at dawn and dusk, without the bulk or weight of larger objectives
• Traditional Porro prism light path produces a rich depth of field, allowing the user to discern the relative distances between objects being viewed
• High refractive index BAK4 prisms deliver a round exit pupil and a crisp and clear image with limited edge distortion
• Aspherical eyepiece lenses correct spherical aberration to produce clear and crisp images, with reduced edge distortion and astigmatism
• Anti-reflection multi-coated optics produce neutral and accurate color fidelity and improve contrast and image brightness
• Wide apparent angle of view reduces the appearance of visible hand shake while offering panoramic views
• 420-foot field of view at 1000 yards

Use and Handling

• Large slip-resistant center focus wheel is easy to manipulate, even while wearing gloves
• Right-eye dioptric correction compensates for individual user’s optical prescription for clearer and sharper views
• 56-72mm interpupillary adjustment range
• Twist-up click-stop rubber eyecups for comfortable use with or without eyewear
• Tripod mountable with optional adapter for hands-free use with reduced vibration and arm fatigue
• 12mm eye relief allows easy viewing without eye fatigue, especially during long observation sessions
• Comfortable 5.3mm exit pupil will completely cover most pupils as they open and dilate in low light for a full and complete view without vignetting
