Kowa Binoculars Genesis Prominar 44 XD 8,5x44

The Kowa Genesis PROMINAR XD 8,5x44 is equipped with Kowa's legendary XD lenses. This allows you to experience razor sharp images with natural colours, a high contrast and breathtaking details that are virtually free of chromatic aberration (colour deviations). The prism system of the Genesis PROMINAR delivers a wide field of view and edge-to-edge sharpness with minimal loss of light, even in low light the XD 8,5x44 provides an immersive experience of your surroundings.

The ultra-compact format ensures that you can take the Kowa Genesis PROMINAR everywhere you go. The magnesium alloy body gives the binoculars the resistance of metal and at the same time the binoculars are extremely lightweight. The binoculars are completely waterproof and filled with dry nitrogen to prevent fogging. A strong rubber armouring makes the Kowa Genesis an extremely durable and reliable pair of binoculars, even in the toughest conditions. Guaranteed performance.

An ergonomic design combined with materials that feel perfect make handling the Genesis PROMINAR a pleasure. Every detail has been considered to bring you not only a pair of binoculars with optics that provide a sublime viewing experience, but also an optical instrument housed in a streamlined non-slip body, finished with high-quality materials to enhance every moment of observation.


Because the roof prisms are treated with phase coatings and C3 coatings, the reflective power is increased to such an extent that a light transmission of more than 99% is achieved. This results in an incredibly clear and sharp image. The Kowa Repelling technology prevents grease, liquid and dirt from accumulating on the surface, making cleaning easier. This KR technology also reduces the risk of scratches on the vulnerable lens surface, because less pressure needs to be applied to remove dirt. The Kowa Binoculars Genesis Prominar is completely waterproof and fully filled with nitrogen gas. This makes it possible for these roof prism binoculars to withstand all temperature fluctuations without the lenses fogging up on the inside.

Each Genesis Prominar model is equipped with Kowa's durable, legendary XD lenses. This high resolution ED glass contains large amounts of the mineral fluorite crystal, the best material available today for light transmission.

Kowa's lens coating technology has been developed over decades, further improving the light transmission properties of all lenses and Kowa's unique KR coating repels dirt and moisture. Enjoy sharp images with natural colours, high contrast and incredible detail, from sunrise to sunset.


Focusing is done with the ultra-sensitive focusing wheel which is easily accessible. Below the right ocular is a dioptric adjustment ring with a special groove to provide extra grip during use. This allows the binoculars to be precisely focused and adjusted for the individual user to provide a clear and sharp image. The ultra-sensitive focusing wheel allows for very accurate focusing.

Field of view

The Genesis Prominar XD 8,5x44 by Kowa has a large field of view with 122 metres at 1000 metres.

This way you do not have to worry about sudden rain or being on or near water. Of course, a manual is included (English and German) and the Genesis 44 comes in a luxurious package.



It is also possible to make photo and video recordings with your smartphone. You connect the right Kowa Adapter Ring with the Kowa Smartphone adapter which is suitable for your smartphone and slide it over one eyepiece of the binoculars.
So it is possible to take high quality pictures by combining the camera of your smartphone with the quality of your Kowa binoculars. The right Adapter Ring for the Kowa Genesis Prominar 44 is the Kowa TSN-AR44GE which you can find at the optional accessories.
