Hoya 40.5mm UX II UV Filter

HOYA's New UX II filters replace the original UX range and continue to provide entry level users with the same high quality and features, including a 10-layer HMC-WR multi-coating with anti-reflection and water-repellent capabilities for fingerprint and smudge resistance (UV model), and Low-profile aluminium frame (UV & CIR-PL models)

The UX II series design concept aims at users wishing to improve their photography. It offers HOYA's famous quality, at reasonable prices, with basic and contemporary features.

'UX' in the series name stands for "User eXperience", inspired by the memorable experiences that users acquire through using these filters. By naming this series 'UX', HOYA aims to offer users better individual experiences through all the activities connected with their photography.

Though not visible to the naked eye, UV light rays are visible to camera sensors and film. They can adversely affect the image when shooting in locations like seasides, landscapes or mountainous environments, resulting in blurred contours or faded and whitish images. UV filters are able to suppress the UV spectrum contained in daylight that causes poor effect on images. This filter can be used with both film and digital cameras and provides more vivid images. In addition, by keeping it constantly attached to the lens, this filter serves as everyday lens protection.

Hoya UX II filters use a low-profile aluminium frame which avoids vignetting when used with wide-angle lenses.
