Ultraviolet (UV) camera filter Kenko Smart Filter MC UV370 Slim 46 mm

Kenko Smart Filter MC UV370 Slim 46 mm is an ultraviolet (UV) camera filter in a slim profile designed to reduce UV light and provide physical protection for the front element of compatible lenses. The filter cuts UV wavelengths shorter than 370 nm and features multi-coating to reduce surface reflections and flare, making it suitable for outdoor photography where UV is prevalent. The slim mount reduces vignetting on compact and wide-angle lenses while maintaining a low-profile fit.

Advantages

The multi-coated glass reduces reflections and minimizes ghosting and flare, preserving image clarity and contrast in bright, high-UV environments. The slim frame lowers the risk of vignetting with wide-angle optics while still offering reliable front-element protection against dust, moisture and light impacts. Because the filter attenuates ultraviolet light below 370 nm, no exposure compensation is typically required when shooting in normal daylight conditions.

Suitable for

• Landscape photography in mountains and open areas
• Beach and snow scenes with strong UV presence
• Everyday outdoor shooting to protect lens front elements
• Use on compact and wide-angle lenses that require a slim filter mount

Key specifications

• Filter type: Ultraviolet (UV) filter cutting wavelengths below 370 nm
• Mount diameter: 46 mm (slim profile)
• Coating: Multi-coated optical surface to reduce reflections and flare
• Color/finish: Black metal frame with optical glass element
• Quantity: Single-piece filter for front-lens protection

How to use

Attach the Kenko MC UV370 Slim filter directly to the lens front by screwing it into the 46 mm filter thread until it is secure but not overtightened. Compose and focus as usual; no exposure compensation is normally required because the filter primarily removes ultraviolet wavelengths below 370 nm without significantly affecting visible light transmission. Clean the filter surface with a soft microfiber cloth and appropriate lens-cleaning fluid to maintain image quality.

Usage recommendations

Use the filter for landscape, beach or snow photography and other outdoor scenes with high UV levels. Prefer the slim profile when using wide-angle or compact lenses to avoid vignetting. Store the filter in a protective case when not in use and avoid overtightening when mounting to preserve the filter thread and lens barrel.
