  • 8.5x Magnification: Immerse yourself in powerful magnification with the Kowa Genesis 44 8.5x44mm Prominar XD Binocular, providing a detailed and close-up view of distant subjects. Ideal for activities like bird watching, wildlife observation, or any scenario requiring a higher level of zoom.
  • 44mm Objective Lens: Strike a perfect balance between compact design and light-gathering capability with the 44mm objective lens. Efficient light transmission ensures bright and clear images in low-light conditions, contributing to a wide field of view and enhanced image resolution for versatile observation scenarios.
  • Kowa Prominar XD Lenses: Kowa's Prominar XD lenses, crafted from extra-low dispersion (ED) glass with characteristics similar to fluorite crystal, effectively reduce chromatic aberration. This optical distortion, causing color fringing, is minimized with the addition of a special dispersion concave lens coating, further enhancing image quality.
  • Schmidt-Pechan Roof Prism and C³ Coating: Kowa's roof prism binoculars feature a Schmidt-Pechan prism with a highly reflective C³ coating, increasing reflectivity by 99% or more across the visible spectrum. This results in brighter and sharper images, as more light is transmitted through the prism and into the lenses.
  • Thixomolded Magnesium Alloy Body: The magnesium alloy body, formed with thixomolding technology, combines lightweight construction with durability. This sophisticated process delivers the strength of a metal body in a lightweight structure, making the binoculars easy to carry and use even in challenging conditions.
  • Kowa's KR Coating: Protecting lenses from dirt and foreign residues, Kowa's KR coating is easy to clean, ensuring the lenses remain in optimal condition for an extended period.
  • Phase-Coated Roof Prism: The Schmidt-Pechan roof surface is phase-corrected, ensuring sharp images with outstanding contrast. This correction eliminates blurring or ghosting, providing clear and detailed images.
  • All-Surface Multi-Coating: The all-surface multi-coated optical system ensures precise color definition for a brighter and sharper image. This coating reduces reflections and improves light transmission, enhancing overall image quality.
  • Waterproof and Fogproof: With a waterproof JIS Protection Class 7 housing and dry nitrogen gas filling, these binoculars resist internal fogging. Use them confidently in wet or humid conditions without worrying about fog obstructing your view.
  • Twist-Up Eyecups: Enjoy easy viewing, even with eyeglasses, thanks to the convenient twist-up eyecups. This feature enhances comfort and usability for a broader range of users.
