Features of binoculars:

• Fully-multi-coated Highly multi-coated optics ensure high light transmittance across the entire visible spectrum and provide high contrast and color rendition in natural tones.
• BAK4 Barium crown is a special type of optical glass, which is used for the production of prisms for optical devices. This material has a low dispersion coefficient (light dispersion), which is less suitable for budget models. As a result, chromatic aberration is noticeably reduced (iris at sharp intervals between the transition from dark to light). In addition, a clear indicator of light bending allows you to eliminate vignetting (the phenomenon of trimming the light beam at the edges), which ensures uniform lightness of the image across the entire field of view.
• Long eye relief design The long eye relief design, which is featured in all Pentax sports optics, allows viewers to see the entire field of view clearly and without force. This is especially bad for those who wear eyepieces and allow them to marvel at the passage of time without additional attention to their eyes.
• Adjustable eyecups. It is easy and precise to adjust to the required and comfortable position, which makes it possible to use the binoculars both with and without eyepieces.
• Possibility of using a tripod.
