Nikon 12×50 Aculon A211 Binoculars

Introduction

With powerful magnification and large objectives, Nikon’s 12×50 Aculon A211 Binoculars are an ideal device for hunters, birders, and outdoor enthusiasts who require an optic that delivers the capability of making long-range observations in even the most challenging light conditions.

The enhanced light-gathering ability offered by the 50mm objectives helps to ensure bright and clear views at dawn and dusk, or when peering into dense underbrush. Anti-reflection multi-coated aspherical lenses, made with environmentally friendly Eco-Glass elements, complement the BAK4 Porro prism light path to deliver high-contrast images with enhanced depth of field without edge distortion, as well as accurate colour fidelity. Despite its 12x powerful magnification, this version of the A211 has a wide angle of view that helps to offset the appearance of visible hand shake that is common with high-power optics such as this, while presenting the user with spacious views.

The Aculon’s sculpted rubber-armoured housing is designed to fit naturally into the observer’s hand and provide secure non-slip handling. It is offered here in a subdued black colour. Twist-up rubber eyecups and a comfortable eye relief enable easy viewing without eye fatigue, especially during long observation sessions. For those who might experience arm fatigue or visible hand shake from holding a high-power/large objective optic, the binoculars can be tripod mounted using an optional adaptor. The combination of image quality and user-friendly design makes the 12×50 Aculon A211 a natural option for long-range glassing in even the most challenging light.

Optical Performance

• Powerful 12x magnification allows for detailed observations of distant subjects
• Large 50mm objective lenses improve light-gathering ability for bright and clear images, even in challenging conditions such as at dawn and dusk
• 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 colour fidelity, and improve contrast and image brightness
• Wide apparent angle of view reduces the appearance of visible hand shake that is common when holding high-power optics such as this
• 272-foot field of view at 1000 yards

Use and Handling

• Large slip-resistant centre 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 adaptor for hands-free use with reduced vibration and arm fatigue
• 11.5mm eye relief allows easy viewing without eye fatigue, especially during long observation sessions
• 4.2mm exit pupil will cover most pupils as they open and dilate in low light for a full and complete view without vignetting
