What is CAT EYE?

✦ Inherited light, created future CAT EYE since 1960 ✦

"CAT EYE" was created in 1960 by Kamakura Koki, which was founded in 1950.
After a long silence, in 2025, the craftsmanship and creative power will come together.
It has been reborn as a "light" for a new era.

Maho LLC, a creative workshop group, has been officially licensed by Kamakura Koki to produce and sell the product, and after 65 years, the "timeless legacy" CAT EYE, equipped with vibration-damping functionality, will shine once again.

The CAT EYE Xross is a vibration-proof binocular that activates its image stabilization function simply by turning it on, allowing you to capture and observe your subject clearly without being bothered by camera shake.
It is fully waterproof, so you can use it with confidence for outdoor activities such as watching sports, stargazing, and bird watching, as well as attending concerts and live performances.

New vibration-proofing function that exceeds world standards.

a. Equipped with the Xross program that identifies the type of shaking and automatically switches to the optimal vibration isolation mode
b. The "Xross Program" uses a digital accelerometer to detect movement and vibration, optimizing image stabilization.
These vibration-proof binoculars are equipped with two vibration-proof modes: one for moving subjects and one for still subjects.
There is no need to switch manually; the Xross program will automatically determine and apply the optimal mode.

Features of CAT EYE Xross

1) Fully multi-coated lens

The objective lens uses ED glass, which exhibits extremely excellent optical performance, and corrects chromatic aberration, which causes color bleeding. In addition, the entire surface is multi-coated to achieve a bright field of view. The prism is coated with a highly reflective derivative multi-layer film and a phase difference correction coating to achieve high contrast and resolution.

ED lens [Extra-low dispersion lens]
Effectively reduces color bleeding

Since the refractive index of light varies depending on the wavelength, the light that passes through the lens will not be focused on the same color. This is called chromatic aberration, and is one of the causes of image quality degradation.
To suppress chromatic aberration, a convex lens with a small difference in refractive index depending on color is combined with a concave lens with a large difference in refractive index depending on color to suppress the occurrence of chromatic aberration.
However, while a combination of normal optical glass lenses can correct the misalignment of light in the red and blue regions, it cannot correct the misalignment of light in other regions.
This is residual chromatic aberration. ED lenses are lenses that use ED (extra-low dispersion) glass, which reduces residual chromatic aberration, making it possible to reduce residual chromatic aberration.
It effectively reduces focus shift, which becomes more difficult to correct as the focal length becomes longer with lenses made of ordinary optical glass.

Characteristics of ED lenses

・Reduces color bleeding and contrast loss. ・Significantly reduces chromatic aberration, a problem with telephoto lenses. ・Effective when observing at high magnification. ・Suitable for observations that emphasize natural color reproduction.

2) Automatic switching to the optimal anti-shake mode

When the switch is turned on, the vibration reduction function is activated.

When the anti-shake function is activated, it automatically switches to one of two anti-shake modes depending on the situation.
X1 mode is suitable for moving objects.
X2 mode is suitable for stationary objects.

3) Designed to last approximately 30 hours on a single AA battery

The power source is AA alkaline batteries, which are easily available at convenience stores and other places around the world. It can be used for approximately 30 hours. There is no need to worry about running out of battery, even during long periods of use such as at concerts.

4) Easy to hold form

The focus ring is located in the center of gravity of the body, making it easy to hook your fingers. The soft and elastic elastomer material allows you to hold the binoculars securely.

5) Focus ring crafted by artisans

The height of the bumps on the focus ring has been adjusted by hand by a craftsman to the nearest tenth. The focus ring fits comfortably in your fingertips, allowing you to accurately capture the subject even with delicate focusing. Please enjoy the feel of a master craftsman's hand.

6) Lightweight model that reduces fatigue

Although it is a large model with a diameter of 42mm, it weighs only 559g (excluding batteries), making it a lightweight model that will not tire you out even when used for long periods of time, such as when walking around all day bird watching.

7) Waterproof design for peace of mind when using it outdoors

Even when outdoors, where you are often faced with adverse conditions such as sudden changes in weather and fluctuations in temperature and humidity, the waterproof design (optical system: IPX7 equivalent) is filled with nitrogen gas, so you can use it with confidence.

8) Comfortable even for eyeglass wearers

The long eye relief design of the eyepiece features a three-stage twist-up type extendable eyecup, making it easy to change the eyepoint and comfortable for people who wear glasses.

Stargazing

Large aperture and large pupil diameter

The larger the lens through which light enters, the clearer the view. For observing the starry sky, where the light is particularly faint, we recommend large-aperture binoculars with an effective objective lens diameter of over 40 mm.

High optical performance

The starry sky looks like a collection of similar "dots" to the naked eye, but when viewed through high-resolution binoculars, you can enjoy the different colors and light of the stars. The CAT EYE Xross series, which has high optical performance of lenses and prisms, is ideal for stargazing because it allows you to see the colors and shapes of celestial bodies clearly and accurately.

Bird watching

Lightweight type reduces fatigue even when used for long periods of time

Birdwatching often involves getting engrossed in chasing wild birds and walking around the field for long periods of time while holding binoculars. Carrying heavy binoculars around under such circumstances can be a strain on the body. The CAT EYE Xross series is lightweight for a pair of binoculars with a large lens, weighing just 559g (excluding batteries), so you can reduce fatigue even when carrying them with other luggage.

Concerts and Live Performances

Even in a dark venue, the facial expressions are clearly visible and the venue is bright.

It's not just about how big the artist appears, but also how they appear. Binoculars that let in a lot of light provide a bright field of view, allowing you to see your favorite artist clearly even in a dark venue.

Watching Sports

Enjoy outdoor sports with peace of mind in changeable weather

The waterproof specification is equivalent to JIS protection class 7, meaning that water will not penetrate inside the device even if it is left underwater for 30 minutes at a depth of 1m. This means you can rest assured even if it suddenly rains while you are watching sports outdoors.

Travel & Outdoors

Detects different types of vibration and automatically sets the optimal mode

The big rocking on the boat and the small rocking when you capture your target dolphins or whales. The CAT EYE Xross automatically detects different types of rocking and sets the optimal vibration-proof mode, making it ideal for sea watching. Of course, it is "waterproof", so you can rest assured even if you suddenly get wet.
