High-End binoculars with PROMINAR lenses

The optical technology of the PROMINAR XD lens has been passed from spotting scope to binocular to bring the world of chromatic aberration free views to binoculars.

– High refractive index prism
The new prism system of the GENESIS 33 allows for a wide field of view and edge to edge sharpness with minimal loss of light. This high refractive roof prism (Bak4 + SK15) offers near total reflectance and when combined with Kowa’s proprietary C³ -coating the ultimate viewing experience is achieved.

– Phase-coated roof prism
The prism is phase-coated to ensure sharp images and outstanding performance.

– Close focus of 1,5 m
Ideal for observation of plants, insects, and other objects within close range.

– Diopter lock
The diopter control is equipped with a locking mechanism that keeps the diopter from accidentally being changed.

– Waterproof and filled with dry nitrogen gas.
JIS 7 = Japanese Industrial Standard / class 7 = Protected against the effects of temporary immersion in water.

The Kowa YF Series Porro Prism Binoculars are a new range from the world-famous Japanese scope and binocular manufacturer. Kowa have infused over half a century of heritage in optics design and production into the new YF Series, which boasts top end features such as Kowa Repelling (KR) lens coatings and 100% waterproofing. The YF Series represents the perfect balance between retro design and modern functionality, with one of its most striking attributes being aesthetic beauty. The YF Series has focussing at its core, and various enhancements have been made to the standard focus functions that are usually found on binocular models. For example, the central focus wheel has been substantially increased in both size and stiffness. Furthermore, a large dioptric adjustment ring has been conveniently positioned under the right eyepiece and purpose grooved to give users extra grip when operating. These improvements ensure that the binoculars can be precisely focused and tailored to a user’s individual preference to give a clear and crisp image.
