Pentax 12.5 x 50 DCF SP, Water Proof Roof Prism Binocular with 4.8 Degree Angle of View, Dark Green & Black, Limited Lifetime USA Warranty.

Featuring high-resolution optics encased in a magnesium-alloy body with JIS Class 6 waterproof construction, these high-performance models are the perfect choice for a wide variety of applications such as close-up viewing, extended glassing, and use in less than ideal weather conditions.

Offering four different magnifications ranging from eight to 12.5 times, the DCF SP models are housed in a nitrogen-filled magnesium-alloy waterproof body and protected with a full-body rubber housing. They deliver exceptional image quality and close focusing with edge-to-edge sharpness, because of the inner-focus optical design incorporating hybrid aspherical eyepiece lenses, high-resolution phase-coated roof prisms, scratch-resistant hydrophobic coating on exposed objective and eyepiece lenses, and multi-coated optical elements.

Their lightweight design and long eye relief provide fatigue-free viewing, even during extended observations. They also come equipped with such user-friendly features as an extra-short minimum focusing distance, a diopter adjuster with lock mechanism, and four-stop helicoid-type eyepiece rings.
