Product Description

Cost effective with superior optical performance

Kowa have infused over half a century of heritage in optics design and production into the YFII Series, which boasts top end features such as Kowa Repelling (KR) lens coatings and 100% waterproofing. The YFII Series represents the perfect balance between retro design and modern functionality, with one of its most striking attributes being aesthetic beauty.

Balancing the traditional Porro prism configuration (providing for a large distance between each objective lens) and a low power magnification (6x or 8x), the YFII series boast an extremely wide viewing field (140m and 132m at 1000m for 6x and 8x respectively). This unique feature allows the user to observe a large field from one position providing a more pleasurable viewing experience.

The YFII Series from Kowa are 100% waterproof. All optical components in the YFII 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.

Serious Binocular

I have never bought a budget binocular. I own multiple so called “alpha” or premium binoculars but wanted to try and find an affordable binocular I could bring to work, keep in my truck and not have to worry. The optical quality of this 6x30 is unbelievable. I’m not an astronomer but for terrestrial use this seems to get very close to some of the better optics available. Focus turns opposite from what I am accustomed to and initially focus **** was very stiff/sticky but it is smoothing up. Although a 6x the depth of field is large enough that there isn’t much need to even change focus. Amazing binocular at this price point and imo as good or better than some costing exponentially more. I will definitely be taking a look at other Kowa products in future. Excellent transaction through All Star Telescope as well!

Great value and quality

I bought these Kowa 8 x 30 binoculars to replace an old pair of compact Nikon binoculars that were unrepairable. The Kowa’s a bit bigger than I had expected for a compact binocular but they are so much more robust and the optics are excellent. They are still a light enough weight to be very comfortable to carry on long treks. I’m very happy with these binoculars!
