KOWA YF 8x30 Binoculars, Black (YF30-8)

Vendor: Kowa



The lightweight design of the KOWA YF 8x30 Binoculars, Black (YF30-8) provides you with the advantage of an exceptionally wide field of view. Add the fully multi-coated lenses and Bak4 prisms for bright views with waterproof and fogproof construction and you have a great economical binocular for beginners and beyond.

All optical components in the YF Series are manufactured from high quality Japanese eco-glass and all surfaces are fully multicoated. These coatings ensure that light transmission, colour definition, brightness and contrast are always performing at a maximum. The binoculars therefore produce clear, vivid and crisp images, creating natural and representative viewing subjects.

The eyepieces and objective lenses are covered in Kowa's unique formula - Kowa Repelling (KR) technology. The KR technology works to stop grease, fluid and dirt from accumulating on the surface of each treated lens, making cleaning much simpler. Furthermore, the KR technology reduces the risk of scratching a fragile lens surface, as less pressure needs to be applied to remove dirt during cleaning.

Unlike the majority of traditional Porro prism binoculars, the KOWA YF 8x30 Binoculars are 100% waterproof. To further optimise this innovative waterproof design, textured surfacing has been added to the binocular body to ensure that when they do get wet, a firm grip can still be maintained. Kowa engineers added a final level of climate protection by injecting and sealing each barrel of the binoculars with nitrogen gas. This measure works to counter any internal fogging of the lenses, a common problem when the binoculars are subjected to temperature change.

The stylish design is ideal for bird watching, nature observation or any other outdoor activity. Depressions placed in the rubber armor make it easy to grip and hold the binoculars.
