The Technology That Shapes Our Products

Ultra-low-reflection coating

NanoAR UV Coating

An anti-reflection coating that reduces unwanted reflections on the glass surface to support clear images. It reduces ultraviolet light while efficiently transmitting the visible light needed for photography.

High-transmittance optical glass

Clear Glass

Made with highly transparent B270 optical glass. Combined with an anti-reflection coating, it achieves high transmittance to deliver light to the lens.

Water-repellent / anti-smudge coating

Hydro Shield Coating

A water-repellent, anti-smudge coating on both sides of the glass makes water droplets and oily smudges easier to wipe away, simplifying everyday care.

Layer-X BASE Filter

Layer-X BASE Filter is an optical filter that attaches to the front of the lens using a standard screw-in mount.
The front surface is equipped with both a built-in magnetic structure and a threaded mount, allowing PLUS filters such as ND, CPL, or cross filters to be layered when needed.
In addition to magnetic PLUS filters, standard lens caps and conventional screw-in filters can also be attached, so the handling remains familiar in everyday use.
The BASE filter blends naturally into daily shooting and serves as the starting point of the Layer-X system, expanding how light can be handled to suit different shooting styles.
