Product introduction

ULTIMA is the highest quality lens filter developed for professional photographers pursuing image quality.

By combining the highest quality optical glass that CORNING boasts with the latest digital vapor deposition coating technology, it realizes optical characteristics that maximize the wavelength range of the light sensor of the digital camera and the highest transmittance.

Adopt grade optical glass to pursue optical performance and used for camera lenses.

Realized remarkably superior optical performance compared with tempered glass used for general lens guard.

A transmittance as close as possible to 100% is realized in the sensor wavelength range [360 - 750 nm] of the digital camera.

It also combines optical properties that effectively cut ultraviolet radiation of 360 nm or less that adversely affect image quality.

Adopting the latest thin frame design with less worry of vignetting by precision processing.

Improved robustness by applying hard anodized processing to aluminum frame.

Pay attention to removability by applying knurling.

As a characteristic of multi coating which thoroughly pursued high transmittance, it may be difficult to fall off if adhered dirt is thirsty.

In that case, do not scrape strongly with cloth etc., we recommend wet cleaning using "HAKUBA lens cleaner 15ml" etc.

Protect the lens with the highest transmittance

Attach a piece of glass in front of the camera lens.

This is the easiest and effective way to prevent garbage and dust and protect it from minor scratches.

However, it is a big challenge for a single glass to affect the optical performance, and a UV cut filter is effective for cutting ultraviolet rays that have a bad influence on the digital image sensor,

The transmittance may be slightly sacrificed or the visible light region may be affected.

Conventional lens guards were not complete as usual filters which do not affect at all from the degree of coating and the use of low homogeneity glass.

"ULTIMA (Ultima)" adopts the optical glass of Corning * as a glass material, and by applying high precision coating on both sides, it has high transmittance in wide band and

Low reflectivity and high efficiency ultraviolet cut are realized at the top class level.

ULTIMA "professional lens guard that takes full advantage of lens performance to every shooting scene suitable for all cameras is the latest digital

Optimized for image sensors.

Features of HAKUBA camera filter ULTIMA

The only lens guard using optical glass

Adopted "Optical Glass" made by Corning Inc. of a grade to be used for lenses of cameras pursuing optical performance.

It achieves remarkably excellent optical performance compared to glass used for general lens guard.

Optical characteristics combining high transmittance and low reflectance

High transmittance is realized in the sensor wavelength range [360 - 750 nm] of the digital camera.

Furthermore, by applying the digital vapor deposition coating, the reflectance is suppressed to 0.3% or less in the wide band (wide wavelength region), and the transmittance is nearly 100% realized.

It also combines optical characteristics that effectively cut ultraviolet rays of 350 nm or less that adversely affect image quality.

Latest thin frame design by precision processing

Adopted the latest wide compatible thin frame design with less worry of vignetting due to precision processing.

Aluminum frame is subjected to matted anodized processing to suppress reflections and scratches as further reflection countermeasures

The sides of the glass were sanitized.

In addition, knurling (slip prevention) processing is given to the side face of the frame, considering the removability.
