UV HD MC Slim C HMC K&F Concept 49mm camera lens filter

K&F Concept 49mm UV HD MC Slim C HMC is a slim ultraviolet filter designed to reduce the amount of UV light reaching the sensor while protecting the front element of lenses with a 49mm filter thread. The filter features multiple anti-reflective coatings to improve light transmission and reduce flare and ghosting, and its slim profile helps to avoid vignetting on wide-angle lenses. It is intended for general protective use and for outdoor photography where UV reduction can enhance clarity in hazy or bright conditions.

Advantages

The slim metal frame and low-profile design minimize vignetting on wide-angle lenses while still providing reliable physical protection against dust, moisture and scratches. Multi-coating (including hard multi-coating) reduces surface reflections and increases light transmission for more accurate color rendering and contrast. The filter screws on to the front of a lens with a 49mm thread for quick installation and removal, maintaining optical performance without adding significant bulk.

Suitable for

• Landscape photography to reduce atmospheric haze and improve distant detail
• Travel and outdoor photography where front-element protection is needed
• Everyday use on lenses with a 49mm thread to prevent scratches and contamination

Key specifications

• Filter type: UV (ultraviolet) optical filter
• Mount size: 49 mm screw thread for lens front
• Frame style: slim, low-profile metal ring to reduce vignetting
• Optical treatment: multi-coated surfaces to reduce reflections and flare
• Primary functions: UV light reduction and front element protection

How to use

Align the filter threads with the lens front and gently screw the filter clockwise until it is finger-tight; avoid over-tightening. Use the filter on any lens with a 49mm thread to provide continuous protection or add it selectively when shooting in bright, hazy or high-UV conditions to reduce atmospheric haze. Clean the filter surface with a microfiber cloth or lens cleaning solution before and after use to preserve coating performance.

Usage recommendations

When using the filter on wide-angle lenses, check for vignetting at the widest focal lengths; the slim profile is designed to minimize this but confirming results on your specific lens is recommended. Store the filter in a protective pouch or case when not in use and avoid touching the coated surfaces to maintain optical quality.
