• Wide apparent field of view (60.3° for 8x42 and 62.2° for 10x42). While realising a wide field of view, the Field Flattener Lens System assures a sharp and clear view all the way to the lens periphery.
• Extra-low dispersion (ED) glass corrects chromatic aberration that causes colour fringing and realises a contrast-rich and high-resolution image
• High-quality multilayer coating is applied to all lenses and prisms while dielectric high-reflective multilayer coating is applied to the roof prisms, achieving a bright view of up to 92% or higher light transmittance, and natural colour fidelity
• Phase-correction-coated roof prisms for high resolution and contrast
• Scratch-resistant coating is applied on the objective lens and eyepiece surfaces
• Long eye relief design ensures a clear field of view, even for eyeglass wearers
• Lead- and arsenic-free glass is used for all lenses and prisms
• Turn-and-slide rubber eyecups with multi-click facilitate easy positioning of eyes at the correct eyepoint
• Dioptre adjustment ring locking system prevents unintentional rotation
• Sturdy, lightweight magnesium alloy body
• Superior waterproof/fogproof performance with a nitrogen-filled body that resists water pressure to a depth of up to 5m/16.4 ft. for 10 minutes and prevents fogging inside the optical system even in low-pressure environments up to altitudes of 5,000m/16,404 ft. equivalent
• Soft-to-the-touch neck strap
• Objective lens caps are integrated to prevent loss
