The manufacturer of the Pentax brand values the high quality of its products, so to eliminate fakes on the market, each unit of Pentax optics is assigned a unique serial number at the manufacturer's factory, thanks to which you can identify the authenticity of the product and be sure that you have a truly original, high-quality optical device.
Binoculars features:
- Fully-multi-coated Full multi-coated broadband optics provide equally high light transmission across the entire visible spectrum and contribute to high contrast and color rendering in natural tones.
- BAK4 Barium crown is a special type of optical glass used to make prisms in optical instruments. This material has a lower dispersion coefficient (light scattering) than the glass used for budget models. As a result, chromatic aberration (iris at sharp transitions from dark to light) is significantly reduced. In addition, a clearly defined refractive index of light avoids vignetting (the phenomenon of cutting off the light beam at the edges), which provides a uniformly bright image throughout the field of view.
- Aspherical lens elements Clarity across the entire field of view is a vital element for comfortable viewing. To achieve this, PENTAX uses aspherical lenses. This is a specially shaped lens that minimizes aberration.
- Inner Focus Optics Design This sophisticated optical design is essential to ensuring the binoculars last a long time. Inner Focus Optics Design significantly increases the reliability of the binoculars. It prevents dust and moisture from entering, protecting the sophisticated optical design from external factors.
- Superb impact resistance The outer rubber coating of the case provides reliable anti-slip protection and shock resistance.
- Adjustable eyecups. Easily and precisely adjust to the desired and comfortable position, allowing you to use the binoculars both with and without glasses.
