SIGHTRONJAPAN Binoculars Roof Prism 8x 42mm Aperture ED Lens SIII 8X42ED II Black SIB25-1800

Specialized dispersion (ED) glass is used in the optical system to correct chromatic aberration, which causes color fringing, and achieves clear, extremely sharp, high-resolution images. By applying a phase difference correction coating to the roof prism and a dielectric multilayer coating to the auxiliary prism, you can enjoy high resolution and a bright field of view. The center focus system and large focusing ring allow for quick and accurate distance adjustment. The long eye relief design allows you to see every corner of your field of vision even when wearing glasses. The twist-up rubber opening provides a comfortable feeling when applied to the eye. Comfortable even when wearing glasses. It has a completely waterproof design, so you can safely use it outdoors in sudden rain or near water. Filling the inside of the main unit with dry nitrogen prevents the internal lens from fogging up. The opposite side is made of sturdy and highly durable die-cast aluminum. The rubber exterior allows for a firm grip. Easy to handle even in cold regions.
