Camera Filter K&F UV 77mm HMC-C – 77 mm UV protective filter for lenses

K&F UV 77mm HMC-C is a 77 mm camera UV protective filter designed to reduce ultraviolet light and protect the front element of compatible lenses. The filter uses multi-coated HMC-C glass to minimize surface reflections and flare while maintaining natural color balance and image sharpness. Lightweight and low-profile, it mounts to any lens with a 77 mm filter thread and is suitable for outdoor, landscape and travel photography where UV reduction and mechanical protection of the front element are required.

Advantages

The HMC-C multi-coating reduces ghosting and flare from bright light sources and improves contrast in scenes with strong sky or backlighting. As a clear protective element, the filter prevents dust, moisture and minor scratches from reaching the lens surface without altering exposure or color rendition. The slim aluminum frame helps avoid vignetting on wide-angle lenses while providing secure screw-in attachment.

Suitable for

• Landscape and nature photography in bright daylight
• Outdoor and travel photography where lens front protection is needed
• General-purpose use to reduce UV haze at long distances
• Use with lenses that have a 77 mm filter thread

Key specifications

• Filter diameter: 77 mm
• Optical element: UV-cut glass with multi-coating (HMC-C)
• Mount type: screw-in filter thread
• Frame material: slim aluminum frame
• Function: ultraviolet light reduction and front-element protection

How to use

Screw the filter gently onto the lens front threading until it seats securely; avoid overtightening. Use the filter whenever you want to protect the front element from dust, fingerprints and light scratches or when shooting in strong daylight to reduce UV haze. Clean the glass with a microfiber cloth and appropriate lens cleaning solution when necessary, and store the filter in its case when not in use to prevent contamination.

Usage recommendations

For wide-angle lenses, check for vignetting after mounting; the slim frame is designed to minimize this risk. When stacking multiple filters or attaching accessories such as lens hoods, ensure compatibility and avoid excessive force on the filter threads.
