OVERVIEW
Designed for both astronomical and terrestrial use, Pentax's 16x50 SP Binocular features large oversized fully multicoated 50mm objectives to reduce reflection and maximize light transmission through the entire optical path. Utilizing the traditional porro prism configuration gives scenes a rich depth of view for an immersive observation experience and provides a comfortable feel in the hand with a lot of surface area to maintain a sure grip. The large objectives and coatings maximize the amount of light getting to the user's eyes for exceptional low-light capabilities, and its high 16x magnification provides an immersive observation experience whether users are bird watching or comet hunting.
The binocular sports a generous 13mm eye relief and the fold-down eyecups seal against the ocular cavity to block stray peripheral light which can dim images. Its over-sized objectives add weight and bias the centre of gravity forward making user fatigue a concern and hand-shake a possibility, so to aid long observation sessions the binocular can be mounted on a tripod using an optional adapter.
