Nikon's new 56mm objective Monarch ATB that possesses the same features and specifications as its popular 42mm brethren but offers the largest objective lens in Nikon's roof prism binocular line-up.

The objective lens size of the new 56mm Monarch also translates into an exit pupil designed to enhance low light performance. Nikon's 12x56 has a 4.7 exit pupil with 22.1 in relative brightness.

As with the entire Nikon Monarch family, the new 56mm Monarch ATB line is fully waterproof and fogproof and features fully multicoated lenses for maximum light transmission and image quality. The new ATBs incorporate Nikon's exclusive Eco-Glass (made without the use of arsenic or lead) for all lens and prism elements. Prisms feature phase-correction coatings and high reflection mirror coatings for superior sharpness and resolution.

Ergonomic styling, mated with a rubber armored exterior, provides added shock resistance and a firm grip, wet or dry to the 7.8 x 5.7-inch Monarch. Turn and slide rubber eyecups, complemented by long eye relief (19.2mm in the 8.5x56, 17.4mm in the 10x56, 16.3mm in the 12x56), allow the binoculars to be used as comfortably by eyeglass wearers as those with uncorrected vision. A large central focus wheel and adjustable diopter make focus easy to achieve and maintain, even while wearing gloves.
