Ultraviolet (UV) camera filter Kenko MC UV370 Slim 49mm, filter size 49 mm, black

Kenko MC UV370 Slim 49mm is an ultraviolet camera filter with a 49 mm thread diameter and a slim profile intended for lens protection and reduction of UV-induced haze. The filter blocks ultraviolet light below 370 nm, improving image clarity in conditions with strong UV presence while remaining neutral for visible light so no exposure compensation is required. The slim metal frame is finished in black and is suitable for lenses with 49 mm filter threads.

Advantages

The MC multi-coating reduces reflections and ghosting while maintaining color neutrality and contrast. The slim construction minimises vignetting on wide-angle lenses and the screw-in design provides secure mounting and straightforward removal. As a dedicated UV filter, it protects the front element of the lens from dust, moisture and minor scratches without affecting metering or autofocus.

Suitable for

• Landscape photography in high-altitude or coastal environments
• Outdoor and travel photography where UV haze is likely
• Shooting on beaches, snowy terrain or bright sunny conditions
• General lens protection during transport and everyday use

Key specifications

• Filter type: Ultraviolet (UV) filter blocking wavelengths shorter than 370 nm
• Mount/thread diameter: 49 mm
• Frame design: Slim profile to reduce vignetting on wide-angle lenses
• Coating: Multi-coated surfaces to reduce reflections and flare
• Color/finish: Black metal frame
• Units supplied: Single filter

How to use

Screw the filter onto the lens front threaded to the 49 mm mounting carefully until it seats snugly; avoid overtightening. Leave the filter on the lens when shooting outdoors to reduce UV haze and to protect the front element. No exposure compensation is required when using this UV filter. Clean the filter glass with a microfiber cloth or lens tissue and a suitable lens cleaning solution to maintain optical performance.

Usage recommendations

For best results in mountain, coastal and snowy environments, use the Kenko MC UV370 Slim 49mm mounted throughout the shoot to minimise atmospheric UV haze and to keep the lens surface protected. Check for vignetting when using very wide-angle lenses and consider removing the filter only when stacking multiple filters or filter holders are required.
