Pentax 8.5×21 U-Series Papilio II Binocular suitable for watching objects both close-up and far away

The compact and lightweight Binocular combines aspherical optical elements and BAK4 Porro prisms to deliver edge-to-edge image sharpness with a 51° apparent angle of view. The optical elements are also fully multi-coated to provide a high transmission of light. With a 8.5x magnification and 21mm objectives, you obtain a notable magnification, insignificant image jitter due to unsteady hands, and a compact form factor. You can easily spot your targets with a wide 6° angular field of view and quickly bring them into focus with a center focus wheel. In addition to observing distant scenes, birds and game, the minimum focus of 20″ allows you to study in detail close objects like butterflies, animal footprints, marks or landscape features. To reduce image jitter while observing distant objects or for prolonged observations, you can connect the binocular to a tripod via an integrated 1/4″-20 socket. The binocular also features a 2.5mm exit pupil, a 15mm eye relief, an interpupillary and a diopter adjustments. Unique Uni-body design enhances durability by locking objective lenses in a single housing and synchronizing the eyepiece movement The binocular is very compact, lightweight, and features a single piece frame that houses objectives, which allows for a synchronized interpupillary adjustment. To accommodate eye glasses wearers, the binocular offers twist-up rubber eyecups. Also included are a carrying case, a neck strap, and eyepiece covers.
