Hama Premium UV 390 Nano Ultraviolet (UV) camera filter 40.5 mm

Hama Premium UV 390 Nano 40.5 mm is a high-end ultraviolet camera filter made from premium UV lens glass. It reduces UV light up to 390 nm to avoid bluish cast and haze, resulting in clearer, sharper images with improved color accuracy. The filter features a multi-layer vapour-deposited NSC18 coating on both sides and a nano lotus-effect coating that repels water, oil and dirt while making the surface easier to clean. The slim metal mount and blackened inner edges minimise reflections and vignetting so the filter can remain on the lens permanently.

Advantages

The NSC18 nine-layer anti-reflective coating on each side ensures excellent light transmission and reduces ghosting and double images. The nano-coating provides a lotus effect for easy cleaning and resistance to misting and contamination. The glass is scratch- and shock-resistant and meets premium HD quality standards. A thin, wide mount design minimises vignette risk and keeps the front element size almost unchanged. An edge sealant protects against soiling and the anodised metal mount retains stable shape across temperature changes.

Suitable for

• Outdoor landscape and travel photography to reduce UV haze
• Portraits and general daylight shooting to improve color accuracy and contrast
• Keeping a protective element on the lens to prevent scratches and reduce repair costs

How to use

Screw the Hama Premium UV 390 Nano 40.5 mm filter onto the front thread of a compatible lens (40.5 mm). Use it during daylight and outdoor shooting to reduce UV-induced haze and improve contrast and colour fidelity. Leave the filter on the lens as a permanent protective element; the ultra-thin mount is designed to minimise vignetting. Clean the filter surface with a microfiber cloth or a lens-cleaning solution when necessary to maintain optical performance.

Recommendations

Use the filter primarily for daylight and outdoor photography where UV light may cause haze; avoid relying on the filter to correct exposure or replace a neutral density filter. Store the filter in a protective case when not in use to preserve the nano coating and prevent scratches.
