Haida Greystone 52mm Multi-Coated UV Filter HD4775

Essential UV protection for 52mm lenses

The Haida Greystone filter absorbs ultraviolet light to reduce the bluish cast common in daylight photography. High-quality optical glass maintains clarity and color fidelity while the ultra-slim aluminum-alloy ring minimizes vignetting risk. It serves as a general shield against dust, moisture and scratches for the front element.

Stacking limited to 52mm front threads

The filter provides 52mm front threads so additional filters can be stacked, yet every extra layer increases the chance of vignetting on wide-angle lenses. Ten coating layers cut internal ghosting and reflections, but they do not eliminate flare from strong off-axis light sources. No water-repellent or oil-repellent treatment is specified.

Upgrades from uncoated or single-coated protectors

Photographers moving from a bare lens or basic protector gain measurable flare reduction and easier cleaning thanks to the multi-coated surface. The jump is most worthwhile for shooters who regularly work in bright daylight or harsh environments where UV haze and physical hazards are constant. Buyers needing a larger thread size or a circular polarizer built in will not find those features here.
