S series consists of a high-aperture binoculars with roof and porro prisms, having a diameter of the lens 40 mm. time-Proven optical design of binoculars SP 8×40 provides obtaining sharp, clear, high-contrast images with virtually no distortion.
Brand multicoated elements to reduce light reflection and glare. Simple focusing system provides accurate and fast tuning, and ocular rings of soft but dense rubber and provide comfort during observations.
Features:
- Rubber coating effectively protects the inner mechanism and optical elements from shock and damage. Binoculars SP 8 x 40 with lens diameter of 40 mm and a large field of view is a good choice for those who need a compact and affordable tool for all types of observations.
- Multilayer ar coating improves light transmission optics eliminates spurious internal reflections, improving brightness, clarity and contrast of the image. Pentax adds a sophisticated multi-layer coating on each surface of the lens and prism all binoculars line of Sport Optics to ensure that you get a bright clear image.
- Prisms of high-quality optical glass BaK4 with high refractive index is used in all Pentax binoculars, that allows to obtain a perfectly smooth and clean image without darkening (vignetting)at the edges.
- Rubber coating effectively protects the inner mechanism and optical elements from shock and damage.
