Introduction

Leica 8×20 Trinovid BCA Binoculars

Inspired by their iconic full-sized counterpart, the Leica 8×20 Trinovid BCA Binocular is outfitted with a moderate magnification and small objectives to deliver the performance users have come to expect from the brand, but in a highly portable and easy-to-carry design.

It is designed with a combination of phase-corrected BAK4 roof prisms, the proprietary HighLux system, and HDC fully multi-coated optics to produce bright and clear colour-neutral images, while fitting comfortably in the hand for long, fatigue-free glassing sessions. The HDC coatings add abrasion-resistance to protect the exterior lens surfaces, and the lenses are also treated with AquaDura coatings which make it easy to clean dirt, grime, oils, sap, and fingerprints without leaving residues that can interfere with views.

Designed to easily fit in a pocket, pack, or purse, the binocular is made with a dual-hinge system that allows the optical tubes to fold and tuck under the closed bridge to ensure the smallest form factor when fully closed. This also provides a wide interpupillary distance adjustment for easier use by those with narrow faces like children and adolescents. Helping to reduce the weight to a mere 8 ounces is an aluminium alloy chassis that is wrapped in a protective slip-resistant armour for a more comfortable feel in the hand. Light, compact, and easy-to-use while delivering bright and clear images, the Trinovid BCA is made to be your constant companion on the trail, at the stadium, or sightseeing around the world.

Optical Performance

• Moderate 8x power magnifies views while preserving a generous field of view
• Compact 20mm objective lenses ensure slim optical tubes to maintain a compact form
• BAK4 roof prisms deliver a round exit pupil, and a crisp and clear image with limited edge distortion
• P40 phase-correcting prism coatings increase light transmission while improving contrast and clarity
• HDC fully multi-coated system has abrasion-resistant and anti-reflection properties to protect exterior lens surfaces, and improve light transmission and contrast
• HighLux-System (HLS) maximises light throughput to improve colour rendition and contrast
• Hydrophobic AquaDura coating on external optical surfaces allows dirt, dust, and fingerprints to be removed easily
• 340-foot field of view at 1000 yards

Use and Handling

• Closed-bridge/dual-hinge configuration provides a sturdy platform for the internal focusing mechanism
• Textured low-profile centre focusing wheel helps to maintain an overall compact form
• Wide 32-74mm interpupillary distance range accommodates use by a wide variety of users especially those with narrow faces like children and adolescents
• 3.5 right-eye dioptric correction allows user to compensate for optical prescription
• Twist-up rubber eyecups for comfortable use with or without eyewear
• 14mm eye relief
• 2.5mm exit pupil
