Hoya UV(C) Digital HMC Filter 52mm

52 mm UV(C) Digital HMC filter for lens protection

This 52 mm Hoya UV(C) Digital HMC filter fits directly onto lenses with a 52 mm thread. It cuts UV haze to improve sharpness and colour balance while shielding the front element from dust, scratches and fingerprints. The slim frame allows it to stay on the lens permanently, making it suited to photographers who want continuous protection without removing the filter for every shot.

Upgrading from an uncoated

Multi-coating on both glass surfaces suppresses reflections that cause flare and ghosting, a noticeable improvement over basic filters that lack such coating. The jump is worth it when shooting into bright light or at night, where uncoated filters add visible artefacts. Photographers who rarely encounter strong backlight or who stack multiple filters may see less benefit from the extra coating layers.

Limits of screw-in filter threads

The filter mounts via a 52 mm male thread, so it only fits lenses with a matching 52 mm female thread; step-up or step-down rings are required for other diameters. Vignetting can occur on ultra-wide lenses if the filter frame protrudes into the image circle, despite the slim profile. Users needing adjustable effects such as polarisation or variable ND must choose a different filter type, as this model provides fixed UV absorption only.
