Hoya UX UV (PHL) 37 mm UV-filter

The Hoya UX UV (PHL) 37mm is a high-quality ultraviolet filter designed to protect your lens while improving image clarity. Part of the renowned Hoya UX series, this filter effectively reduces atmospheric haze and blocks UV light below 370nm, resulting in sharper, more contrast-rich photographs. Its multi-coated optical glass ensures over 98% light transmission with minimal reflection, making it an ideal choice for both digital and film photography.

Advantages

This UV filter offers dual benefits: lens protection and image enhancement. It safeguards your front lens element from dust, scratches, and moisture without compromising image quality. The slim aluminum frame prevents vignetting on wide-angle lenses, while the water-repellent and anti-static coatings make cleaning easy and reduce dust attraction. With no exposure compensation needed (filter factor 1), you can leave it on permanently.
