PENTAX SD 7x42 ED Binoculars for nature and astronomical observation, full multi coating, waterproof construction

Bright and clear view of the subject with minimal glare and ghost images, thanks to the application of a full multi-coating process to all lens surfaces and a special coating designed to optimize light transmittance. ED (Extra-low Dispersion) optical elements effectively compensate chromatic aberration, delivering a sharp, high-contrast, blur-free image. Large 42-millimeter diameter objective lenses deliver a bright, clear view, even in unfavorable lighting conditions, such as in twilight. Suitable for a wide range of applications — from bird watching, nature and astronomical observation to the viewing of sports events and concerts. Easy-to-operate diopter adjustment mechanism with a non-slip, ring-type adjuster. Waterproof construction equivalent to JIS Class 6 standards for dependable use in adverse weather conditions. Nitrogen-filled design to prevent interior lens surfaces from fogging caused by sudden temperature changes. Easy mounting on a tripod, in combination with the optional TP-3 Tripod Adapter.
