HOYA Filter 72mm Alpha II Multi-Coating Protector camera filter

72 mm protector filter

The HOYA Alpha II is a 72 mm clear glass filter designed to stay on the lens for everyday protection. It uses Hoya clear glass with six layers of multi-coating to maintain 93.7% light transmission. A thin matte black frame keeps the profile low and avoids vignetting on wide-angle lenses. Front threads allow stacking or a lens cap.

For lenses with 72 mm thread

This filter suits photographers who want a lightweight, affordable shield against dust, scratches and fingerprints on 72 mm threaded lenses. The multi-coating reduces reflections without adding colour cast. Buyers who need UV absorption, water-repellent top coats or hardened optical glass should look at higher-tier series, as the Alpha II omits those premium features.

93.7% light transmission

The measured 93.7% transmission is the key specification that shows how little light the filter absorbs. Six coating layers on clear glass keep exposure settings virtually unchanged while the thin frame prevents corner darkening. If your workflow demands maximum flare resistance or environmental sealing, a filter with additional top-layer treatments would be required.
