ULTIMA is the highest quality lens filter developed for professional photographers seeking image quality.
CORNING's premium-quality optical glass combined with the latest digital vapor coating technology ensures optical properties and maximum transmittance that make full use of the light reception sensor wavelength range of digital cameras.
Uses grade optical glass used in camera lenses and other applications for optical performance.
It provides a much better optical performance than tempered glass used in typical lens guards.
Digital camera's sensor wavelength range (360-750nm) provides 100% transparency. It also has optical properties that effectively block UV rays below 360 nm (360 nm) which adversely affects image quality.
Adopts the latest thin frame design that reduces the risk of vignetting due to precision processing. Hard anodised aluminum frame for improved durability.
Knurled for easy on and off.

The characteristic of the multi-coating that thoroughly pursues high transmittance, the dirt that adheres to dirt may become difficult to fall off. In such cases, it is recommended to use a wet cleaning method with a 0.5 fl oz (15 ml) HAKUBA Lens Cleaner.
