Key Features
- 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 up to 92% or higher light transmittance, which enables a bright view 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. Interchangeable objective rubber rings without caps are included and can be switched according to applications.
 - Optional tripod adapter enables attachment to a tripod [TRA-3/Adaptor H (hard type)]
