HOYA 77mm HDX UV Filter

HOYA HDX UV filter 77mm

The 77mm HOYA HDX UV filter from Hoya is a UV filter of absolute top quality. HOYA even describes the HDX series as 'Best filter performance in history'. The filter is made of special optically hardened glass and therefore has 4x the tensile strength of traditional filters. The filter is specially made for today's digital market, in which the sensors are more sensitive to reflected light than in the analogue era. The Hoya HDX filter is equipped with special coatings that reduce internal reflections and thus provide a clearer, brighter and sharper image. The multi-coating in the HDX filter consists of 8 (!) layers on each side. This ensures maximum optical performance and a light transmission of no less than 99.4%. This also ensures that the filter is water, dirt and scratch resistant, making it more pleasant to use and last longer.

Finally, the mount is made of very durable black anodized aluminum that completely closes the filter glass, so that moisture and light cannot penetrate undesired. This mount is also extra thin, so you don't suffer from vignetting, as is the case with a large part of the cheaper filters. This makes it extremely suitable for use with wide-angle lenses.
